What should a welder's cover letter actually say?

Where this letter actually gets read

Most welding jobs aren't filled by someone reading a covering letter start to finish behind a desk. They're filled by a shop foreman, a fab shop owner, or a project superintendent who's short-handed and needs someone who can lay a clean bead now. In a lot of fab shops, structural steel contractors and pipeline crews there's no dedicated recruiter reading applications — the person deciding is also running the floor. That changes what the letter is for.

If you're applying through a union hall dispatch or an out-of-work list, a covering letter often does nothing at all — dispatch runs on seniority and ticket, not prose. If you're applying direct to a fabrication shop, a shipyard, a pipeline contractor or an OEM welding department, someone does read it, but usually for thirty seconds, and usually to confirm two things before they even open your CV: what processes you run, and whether you're qualified to weld to the code or position the job needs.

Where it's skipped almost entirely: any job that's going to put you in front of a test coupon before an offer is made, which is most of them. If the employer is going to sit you down for a bend test or a visual and radiographic check on a sample weld, no letter changes that outcome. Its job is to get you to the test, not replace it.

The one or two things a foreman actually wants answered

Read the advert again and find the process and position it names. "GMAW/FCAW, flat and horizontal" is not the same job as "GTAW stainless, 6G pipe." A generic line about being an "experienced welder with strong attention to detail" answers neither. What the reader wants to know, in the first two or three lines, is:

1. Which processes you actually run day to day — MIG (GMAW), TIG (GTAW), Stick (SMAW), flux-cored (FCAW) — and on what material: mild steel, stainless, aluminium, chrome-moly.
2. What you're qualified for against the code the job runs to. That might mean an AWS D1.1 structural steel ticket, ASME Section IX for pressure vessel or pipe work, a coded pipe welder ticket, or a specific 3G/4G/5G/6G position qualification. If you hold current welding certifications, name the issuing body and roughly when you were last tested — certifications lapse and shops know it.

If the advert names a code or a position and your letter doesn't answer it, you've left the reader to dig through your CV to find out, and a lot of them won't bother. One sentence doing that work outperforms three paragraphs about work ethic.

The second thing worth answering, where it applies, is availability and mobility. Much welding work is project-based — turnaround, shutdown, pipeline spread work, structural erection — and a shop hiring for a shutdown wants to know fast whether you can start on their timeline and travel to site. If you can, say so plainly. If you can only work local shop hours, say that too, rather than let them assume you're a fit for travel work and find out at the interview.

Be honest about how much weight it carries

For most welding jobs, the letter is a small filter, not a decision-maker. What actually gets you hired is your ticket, your test coupon, and a work history showing you've run the specific joint configuration and material the job needs. A shop short-handed on a stainless pipe job doesn't care how well you write; it cares whether you can run a clean root pass on 6G pipe and pass an X-ray. No letter substitutes for that.

Where the letter earns its place is at the margin — when two candidates hold similar tickets and one has written two sentences that show they read the advert and know what the job actually involves, while the other sent the same paragraph to twenty shops. It also carries more weight for roles a step up from production welding — welding inspector, WPS or procedure qualification work, lead hand, fabrication supervisor — where someone needs evidence you can read a drawing, follow a written procedure, and write a report, not just run a torch. If you're applying for one of those, put more into it.

For a straightforward "welder wanted, day shift, GMAW, must have own hood and gloves" advert at a local shop, don't overwrite this. A short, specific letter beats a long one — the reader is not evaluating your prose.

What to actually put in it

Keep it to a page, and build it around what the advert asked for rather than your career story:

• Open by naming the specific process, material and position the advert asks for, and confirm directly that you do that work now or have done it recently. "I currently run GMAW and FCAW on structural steel, flat and horizontal, and hold a current AWS D1.1 qualification" says more in one line than a paragraph of adjectives.
• State your ticket or certification directly — issuing body, and qualification date if recent. If you're coded for pipe (say, 6G carbon steel to ASME Section IX), say so explicitly rather than leaving it for the CV to surface.
• If the job involves working to written procedures — a WPS, a drawing set, an NDT requirement like radiographic or ultrasonic inspection — say you've worked to procedure before, not just "welded parts."
• Mention your own equipment if the advert or trade norm expects it — hood, leathers, gloves, sometimes your own machine for site work. If it's asked for, confirm it in one line.
• Close with availability — start date, shift pattern, willingness to travel for shutdown or turnaround work if relevant — and a direct request for a test or interview.

That's the whole letter. It doesn't need a paragraph about why you got into welding, and it doesn't need to restate the CV.

What to leave out

Drop generic trade language that would fit any manual job — "hardworking," "reliable," "team player" tell the reader nothing they can act on, and every other applicant has written the same words. If you want to signal reliability, do it with something specific: years on your current ticket, a project finished on schedule, a shutdown worked through without a callback for rework.

Don't claim a process or position you haven't actually run recently. A foreman who puts you in front of a test coupon will find out inside five minutes, and a mismatch between what the letter says and what the test shows is worse than leaving it out.

Don't apologise for gaps in your work history unless the advert specifically asks about them. Seasonal and project-based work is normal in this trade and most hiring managers know it — a gap between a shutdown ending and the next one starting doesn't need explaining away.

What to do next

Pull up the actual advert and find the process, material, position and code it names — that's the sentence your letter has to answer first. If the advert names none of that, it's probably not worth much time; a vague advert usually gets a vague screening process regardless of what you write. If you're sending the same handful of sentences to shop after shop and hearing nothing back, the letter is rarely the reason — it's more often the ticket you don't hold yet, or the test you haven't been given a chance to sit. jobmarket.pro reads the specific advert, checks it against your actual certifications and process experience, and writes the application to match that job rather than a generic one.
