What Does a Welder Do? Duties, Skills & Requirements

A welder job description typically lists one core function and a dozen variations on it: fabricating and repairing metal parts using heat, filler material, and pressure across construction sites, manufacturing plants, and shipyards, where shipyard welding apprenticeship programs build the pipeline of new welders. Median pay for the trade sits near $53,750 a year nationally, but the spread between a production welder running the same seam all shift and a certified pipe welder qualified on 6G joints can top $30,000.

That gap is the real tension employers and job seekers both navigate: the title "welder" covers wildly different duties, certification demands, and physical requirements depending on specialty and industry.

Employers who write vague postings tend to attract mismatched applicants, which is why specificity in duties, tools, and required tickets matters from the first line.

What Does a Welder Do? Core Daily Responsibilities

Every welder job description balances two things at once: the craft of joining metal cleanly and the discipline of following a process from paper to finished part. A welder who only knows how to strike an arc but can't read a print or catch a defect before it ships won't last long on a crew, and that's why employers write job descriptions around a full workflow rather than a single skill.

A Typical Workday

Most shifts start with a print. The welder reviews blueprints or work orders to confirm joint types, weld symbols, material specs, and tolerances. From there it's material prep: cutting, fitting, grinding, and cleaning the base metal so the weld will actually hold. Then comes the welding itself, followed by a self-inspection or handoff to a quality inspector, and finally equipment shutdown and maintenance before the next job starts. That sequence, print to prep to weld to inspect to maintain, is the backbone of nearly every welder job description posted.

The Five Core Duties

Strip away industry jargon and the job comes down to five repeatable duties:

• Blueprint and specification reading: Interpreting welding symbols, joint diagrams, and material call-outs before any metal gets cut.
• Material preparation: Cutting, beveling, clamping, and cleaning surfaces so joints fit within tolerance.
• Welding execution: Running the actual weld using the specified process and technique to meet code or print requirements.
• Inspection and quality control: Checking bead appearance, penetration, and dimensions, sometimes with gauges or nondestructive testing support.
• Equipment and tool maintenance: Keeping machines, torches, and gas systems in working order and reporting problems before they cause downtime.

A resume built around these five duties tends to read stronger to hiring managers than one that just lists "welded parts," because it shows the applicant understands the whole job, not just the arc time.

How Duties Shift by Process and Specialty

The general framework holds across the trade, but the day-to-day details change with the process. A MIG welder on a production line with proper MIG welder settings may spend most of the shift running repetitive short welds at high speed, with inspection built into the pace of the line. A welder doing TIG welding on aerospace or food-grade stainless work moves slower and more deliberately, with heavier emphasis on cleanliness and bead consistency. Stick welders working structural steel or field repair often deal with outdoor conditions and thicker material, while flux-core is common on heavy fabrication and construction where speed and penetration matter more than a polished finish.

Specialty matters just as much as process. A structural welder's daily duties lean toward steel erection and fit-up on large assemblies, a pipe welder's toward precise, code-governed joints that will carry pressure, and a fabrication welder's toward building custom parts from raw stock. The core five duties don't change, but the emphasis, tools, and pace do, which is why job descriptions for these roles rarely read identically even when the title says simply "welder."

Welding Skills and Physical Requirements Employers Demand

What skills and physical abilities do employers actually screen for when hiring a welder? The answer splits into two categories: technical competencies you build through training, and physical demands your body has to sustain shift after shift. Understanding both helps you match yourself to the right jobs through welder job boards and write a resume that speaks to what hiring managers need.

Technical Skills That Get You Hired

Welding is a thinking trade as much as a manual one. The core technical skills most employers expect include:

• Blueprint and symbol reading: Interpreting weld symbols, joint details, and fabrication drawings so you lay down the right weld in the right place.
• Shop math: Measuring, calculating angles, working in fractions and metric units, and figuring material dimensions accurately.
• Metallurgy basics: Understanding how carbon steel, stainless, aluminum, and other metals behave under heat so you can control distortion and avoid cracking.
• Process-specific technique: Real proficiency in the processes a job calls for, whether that is stick (SMAW), MIG (GMAW), TIG (GTAW), or flux-cored, often across multiple positions.

Many of these skills are what you demonstrate on a certification test, and they are worth listing explicitly on a resume rather than assuming an employer will infer them.

Physical Requirements and Coordination

The Bureau of Labor Statistics groups welders, cutters, solderers, and brazers together and describes the physical profile as manual dexterity, physical stamina, physical strength, a steady hand, and hand-eye coordination.¹ In practice that means holding a stable arc while reading the puddle, lifting heavy metal or equipment (job postings frequently cite 50 pounds or more), and sustaining awkward positions: bending, stooping, standing for long stretches, and overhead work on scaffolds or platforms. Confined spaces and outdoor weather are common in field settings.¹ These abilities apply to the combined occupation, so exact welder requirements vary by employer and specialty rather than following one universal standard.

Safety Awareness and PPE

Safety is a hireable skill in its own right. Welders face burns, ultraviolet and infrared arc radiation, flying debris, toxic fumes and gases, electrical shock, and excessive noise, alongside risks like hot surfaces and gas cylinder handling.² OSHA addresses these hazards under 29 CFR 1910 Subpart Q, with standards spanning general industry, maritime, and construction depending on the site.³ Fume control typically relies on local exhaust at the source or adequate ventilation.⁴ Employers value welders who practice Welder Safety and use PPE consistently and understand hazard controls, so listing comfort with respirators, ventilation practices, and confined-space awareness strengthens any application.

Welder Certifications: AWS, ASME, and API Requirements

Most welding jobs don't require a government license, but employers almost always want proof you can run a specific process, in a specific position, on a specific material, to code. That proof usually comes from one of three Welder Certifications systems.

AWS D1.1 for Structural Work

AWS D1.1 governs structural steel welding and is the standard most bridge, building, and general fabrication shops test against. Qualifying means welding a coupon under an approved procedure, then passing visual inspection plus bend or other acceptance testing.¹ Common formats are a combined 3G SMAW Certification and 4G SMAW Certification test for structural positions, or a 6G pipe test when employers want proof of all-position capability.¹ The 6G is generally considered the harder screen and tends to lead to more qualifying options.

D1.1 credentials are typically employer-bound rather than a portable license. They lapse for a given process after about six months without documented use, so continuity records matter as much as the original test.¹ AWS also publishes a formal exam path (roughly 445 to 540 dollars² depending on membership, plus separate training materials often in the 298 to 397 dollar range³) through its Certified Welder program, coded QC47, which runs through accredited test facilities.⁴

ASME Section IX for Pressure Vessels

ASME Section IX covers procedure and performance qualification for pressure vessels and piping. Employers usually have you weld a coupon to an already-qualified procedure, then evaluate it to code. A 6G pipe test is a frequent screening choice here too, though the exact joint design, coupon size, and referenced construction code vary by employer and contract.⁵ There's no single published fee for Section IX testing since labs, schools, and employers each set their own costs.

API 1104 for Pipelines

API 1104 applies to pipeline welding and is likewise a performance test on pipe coupons, judged by visual inspection plus bend testing or radiographic and other nondestructive evaluation depending on the job. Like Section IX, it's typically employer-bound, and 6G is common in pipeline and utility hiring.⁵

What Employers Actually Check

Beyond the code name, hiring managers care about process (SMAW, FCAW, GMAW, SAW), position (1G through 6G), material and thickness, and continuity within the last six months.¹ Expect to show a WPQR, a continuity log, and photo ID.¹ Entry-level candidates without a formal certificate aren't automatically shut out: many shops will run their own in-house qualification test on their own procedure before hiring, which can be a practical entry point while you build toward AWS, ASME, or API credentials.

How to Become a Welder: Apprenticeship Vs. Trade School

Most welding apprenticeships in 2026 run 3 to 5 years¹, combine roughly 2,000 hours of paid on-the-job training per year¹ with about 144 hours of classroom instruction², and require only a high school diploma or GED plus a minimum age of 18. Formal trade school is not a prerequisite for the apprenticeship itself, because the apprenticeship is the training.¹

Union apprenticeships: structured pay and benefits

Union routes typically run through a local hall or a Joint Apprenticeship and Training Committee (JATC). They have fixed application windows, a published wage ladder, and benefits like health insurance, pension, and training fund contributions. Duration varies by trade:

• UA Pipefitters: 5 years, U.S. Department of Labor registered, with tuition-free classroom instruction in many locals.⁴
• Ironworkers: roughly 3 to 4 years.⁵
• Boilermakers: about 4 years.⁵

First-year union apprentices' entry level welder salary commonly starts at 40 to 60 percent of the journeyman wage in their local, with raises tied to hours completed and skill milestones.²

Nonunion and employer-sponsored routes

Nonunion apprenticeships are usually employer-driven and more variable. They may still be state- or DOL-registered, but wage progression, benefits, and training structure depend on the sponsoring contractor. Program length runs anywhere from 1 to 4 years. According to Associated Builders and Contractors, nonunion registered apprenticeship participation grew 60 percent between 2020 and 2025, compared with 21 percent for union programs, so this side of the market is expanding quickly.

Entry requirements to expect

Most sponsors screen for a similar baseline:

• Age: at least 18 for the majority of programs.
• Education: high school diploma or GED.
• Physical exam: ability to lift, climb, and work in awkward positions; some sponsors require a drug screen.
• Aptitude: basic math and mechanical reasoning tests are common; prior welding experience is usually not required for entry-level slots.

Trade school vs. apprenticeship

A standalone program at one of the welding trade schools typically runs 7 to 24 months and awards a certificate or associate degree. It can be the fastest way to build torch time before entering the workforce, and some apprenticeship applicants use short courses to strengthen their application. But formal schooling is not required if the apprenticeship already combines paid work with related technical instruction.¹ The credential that matters at the end is completion of the apprenticeship and the welding certifications earned along the way, not a diploma from a separate school.

Tools and Equipment Welders Use by Process

The table below compares commonly used tools, equipment, and safety gear across five welding processes. Equipment lists reflect general industry practice and may vary by employer, job site, and specific application.

Welder Work Environment and Schedule: Industry Differences

Where a welder clocks in changes almost everything about Welding Jobs, from the shift pattern to the hazards on the safety briefing. A structural welder on a highway overpass, a shipyard welder inside a ballast tank, and an aerospace welder building titanium airframe components are all doing skilled fusion work across different Welding Processes, but their daily conditions barely resemble each other.

Construction and Fieldwork

Construction welders spend most of their time outdoors or in partially enclosed job sites, often on scaffolds, lifts, or structural steel at height.¹ Schedules tend to run Monday through Friday during stable phases of a project, but overtime becomes common as deadlines close in, and the work location itself shifts as crews move between jobsites.¹ Weather exposure, falls, and electrical hazards are constant considerations alongside the usual fumes and sparks.²

Manufacturing and Production Plants

Manufacturing welders work in controlled indoor factories², which makes this the most schedule-structured branch of the trade. Plants commonly run two or three shifts of 8 to 12 hours to keep production lines moving around the clock, so evening and weekend rotations are routine and overtime is frequent.² Travel is minimal since the job is plant-based, but hazards shift toward machinery, hot materials, and noise rather than weather or falls.²

Shipbuilding and Confined-Space Work

Shipyard welders work in dry docks and aboard vessels, frequently inside confined spaces such as ballast tanks and below-deck compartments where visibility and ventilation are limited.³ Many shipyard postings advertise a standard Monday-through-Friday, 40-hour week⁴, though project deadlines can still push extended hours. Travel between ports or job sites is more common here than in manufacturing,⁵ and confined-space entry procedures add a layer of hazard beyond the usual burns and fumes.³

Aerospace and Precision Fabrication

Aerospace welders operate in tightly controlled production environments built around precision metallurgy, working with materials like titanium and Inconel that demand strict process control.⁶ Travel is limited and the setting is more shop-like than a construction site or shipyard, though overtime can still climb when production demand spikes.⁶

Shared Conditions

Across every specialty, welders typically work full time, often exceeding 40 hours a week, and contend with fumes, burns, intense arc light, noise, and electrical exposure regardless of industry.

Welder Duties by Specialty: Structural, Pipe, Production, and Fabrication

Welder duties change with the specialty and work setting. Structural and fabrication welders read blueprints, prepare metal, fit components, and inspect finished joints, while pipe welders focus on alignment and joint preparation and production welders repeat assigned product builds.

Welder Salary Overview: National Data and Employment

The U.S. Bureau of Labor Statistics reports national wage and employment estimates for three welding related occupations. Median annual pay ranges from about $47,920 for machine setters, operators, and tenders to $53,750 for welders, cutters, solderers, and brazers. Actual pay varies by specialty, experience level, and location.

Salary Snapshot: Highest-Paying State for Welders

Alaska recorded the highest median annual wage among states for welders, cutters, solderers, and brazers in the latest BLS data.

Welder Pay by Specialty and Experience Level

Structural welders typically earn between $40,000 and $75,000 or more a year, while pipe welders often see the widest range of any specialty, from around $46,000 up past $81,000 for those running 6G pipe and high-alloy processes. Production and fabrication welders tend to sit closer to the middle, with production roles generally landing between $39,000 and $60,000 and fabrication work between $42,000 and $65,000. These figures blend national benchmarks from the Bureau of Labor Statistics with specialty-level salary survey data, since the BLS does not break its own wage tables out by structural, pipe, production, or fabrication welding specifically.

Experience Changes the Math

Entry-level welders nationally average close to $18.91 an hour, while mid-career welders climb to roughly $21.73. Pipe welding shows a similar arc: entry-level pipe welders average around $22.33 an hour, moving to about $25.96 in the early-career stage as 6G and code-welding skills solidify. On the structural side, entry-level ironworkers generally start between $40,000 and $55,000, experienced ironworkers move into the $60,000 to $75,000 band, and certified or foreman-level ironworkers can clear $80,000. Across welding career paths, the pattern holds: base pay rises steadily with tested skill, but the biggest jumps come when a welder adds certification, inspection knowledge, blueprint reading for fitters, or supervisory responsibility rather than tenure alone.

What Pushes Pay Higher

A few variables consistently separate the lower end of these ranges from the upper end:

• Certifications: AWS, ASME Section IX, and API credentials don't guarantee a fixed dollar bump, but they open the door to the higher-paying work that does, like pressure vessels, pipelines, and code-stamped fabrication.
• Travel and per diem: Traveling welders often earn 30% to 50% more than shop-based peers, with hourly rates spanning roughly $25 to $55 and per diem allowances of $75 to $180 a day layered on top of base wages, not folded into them.
• Overtime: Field and industrial welding jobs frequently include overtime hours that meaningfully raise total annual earnings beyond a quoted base rate.
• Location and industry: Regional demand, union agreements, prevailing-wage projects, and specialized industries like aerospace manufacturing all shift the range up or down.

Because per diem and overtime are separate from taxable base wages, it's worth comparing offers on an apples-to-apples basis, hourly rate against hourly rate, before weighing allowances and bonuses. Readers researching which certifications tend to lead to higher pay can review the certification test guides for AWS, ASME, and API.

Common Questions About Welder Job Descriptions

These are the questions employers and career changers ask most when reviewing a welder job description. The answers below summarize typical duties, entry paths, credentials, and pay based on current national data and certification guidance.

What are the 5 main duties of a welder?

A welder's core duties typically include reading blueprints and drawings, measuring and aligning parts, inspecting base materials for defects, welding to specifications, and monitoring the process to maintain quality. Many employers also expect welders to set up equipment, clean welds, and follow safety procedures, but those five duties cover day-to-day production work.

Is formal schooling necessary, or can someone enter through an apprenticeship?

Formal postsecondary schooling is not universally required. A high school diploma or equivalent is the typical entry point, and many welders enter through registered apprenticeships that combine paid on-the-job training with classroom instruction. Apprenticeship programs often run 4,000 to 6,600 hours,¹ while trade school or community college can also prepare candidates for entry-level roles.

Which welding certifications do employers commonly require?

There is no single certification every employer requires. The AWS Certified Welder (CW) is the most common entry-level credential, often alongside AWS D1.1 structural qualification.² Some employers prefer the AWS Certified Welding Fabricator for fabrication roles, while the Certified Welding Inspector is relevant for quality control and oversight.²³ Many jobs also require an employer-specific practical test for the exact process, position, material, and code.⁴

How much do welders earn by specialty and experience?

National data for welders, cutters, solderers, and brazers show a median of $53,750 per year, or $25.84 per hour, as of May 2025. Pay varies by specialty, location, certs, and experience , for example, underwater welder salary , but no reliable 2026 national breakdown by specialty and experience is available from federal data. Certain roles, such as certified ironworker welders or foremen, can exceed $80,000 annually.⁵
