A structural metal fabricator (often called a fitter) turns drawings into real steel assemblies: beams, columns, trusses, platforms, frames. You read a blueprint, lay out and cut the steel, fit the pieces together to tight tolerances, tack them, and often weld them. Fitting is the skill shops prize most, because a good fit makes good welds and a straight finished piece. You don't need a degree. About 95% of workers have a high school diploma or less, so hiring is based on what you can show: reading prints, measuring accurately, working safely, and fitting parts square.

Stage 1 of 3 · about 12 weeks
Work safely in a shop, do shop math, read basic prints, and make accurate cuts and tack welds on practice pieces.
Shop safety and PPE
Steel is heavy, sharp, hot, and sparks. Employers hire people who are safe first, because one injury shuts down a bay. Knowing hazards also makes you faster, since you do not stop to recover from mistakes.
Shop math and measuring
Every fit depends on measurement. A 1/16 inch error repeated across a long beam becomes a part that does not bolt up. Fractions, decimals, and angles are the daily math of the job.
Reading blueprints and weld symbols
The drawing is your boss. It tells you the material, length, hole size, and weld type. Misreading a weld symbol means rework or a failed inspection.
Layout and cutting
Cutting and layout turn raw stock into correct parts. Poor layout cannot be fixed later by good welding.
Tack welding and basic welding
Fitters tack parts together before final welding. A good tack holds position and is strong enough to resist pull from the full weld, so you need basic welding comfort.
