What a welder really does
You turn drawings into joined steel, check your own work like an inspector would, and hold the line on safety when the schedule pushes.

What the work involves
What fills a typical week for welders, built from O*NET occupation data.
- Read shop drawings and work orders to plan how each piece gets fit and welded.
- Pick the process, filler wire or rod, and settings for the metal type and thickness in front of you.
- Prep surfaces, then fit, clamp and tack parts square before running the final welds.
- Weld in flat, vertical and overhead positions, watching heat so parts do not warp.
- Inspect and measure finished welds, grind off slag and spatter, and fix what does not pass.
- Mark every piece with its job number and piece mark so it ships to the right place.
- Flag bad material or a misbehaving machine to the foreman before it becomes a scrapped part.
What the days are like
What people in the job know
- The schedule is always pushing. Fabrication shops quote ship dates, and the welder is where the time goes. Time pressure: 72% every day (O*NET Work Context)
- It is more of a team job than people expect. You talk with fitters, the foreman and inspectors all day, but you rarely deal with customers or email. Face-to-face discussions: 67% every day; E-mail: 74% never; Deal with external customers: 61% not important at all (O*NET Work Context)
- Fumes, noise and small burns are part of a normal day, not an accident. Gear is not optional. Exposed to contaminants: 62% every day; Minor burns, cuts: 48% every day; Wear common protective equipment: 86% every day (O*NET Work Context)
- The shop floor is not climate controlled, so summer and winter both follow you to work. Indoors, not environmentally controlled: 59% every day; Very hot or cold temperatures: 33% every day (O*NET Work Context)
- Precision matters more than speed when it counts. A weld that looks fine but is undersized can fail an inspection or a structure. Importance of being exact or accurate: 56% extremely important; Consequence of error: 33% extremely serious (O*NET Work Context)
How people get into it
O*NET Job Zone 2 (some preparation). Most new hires have a high school diploma (54% of workers surveyed) and some hold a post-secondary certificate (12%), usually from a vocational welding program. Skill is built through on the job training under experienced welders, and many shops give a hands on weld test before hiring.
The Firstday trial, easy to hard
Three simulated tasks with AI coworkers who message you, react to your work and coach with questions. Nobody scores you.
What the trial can't show: This trial does not cover the physical craft of welding: striking and holding an arc, puddle control, hand steadiness, working overhead in a hood, or the heat, fumes, noise and fatigue of a full shift. Those take months of booth time to learn. It covers the reading, planning, inspection, material and safety decisions, and shop communication that surround the welding itself.
Reading about it is one thing.
Find out how the work feels to you before you spend on a degree, course or job change. Your first trial is free.
