Welder skills: what to learn first, and what can wait

A foreman can tell within a few questions whether you know how to set up a machine. The skills below are sorted by when they pay off, from the ones that get you a shot at the booth to the ones that get you the lead's job. Pay moves with the shop and the season, but a skill you've built in your hands stays with you.

Step one

Gets you the interview

Running MIG and stick on carbon steel plateGMAW and SMAW on mild steel are what most fab and repair shops put you on first. Be specific about what you've run: short-circuit MIG on sheet, spray transfer on heavy plate, or low-hydrogen stick rod kept dry in a rod oven. Saying you know welding tells a foreman nothing.

Setting up your own machinePicking wire speed and voltage for the material thickness, switching polarity between stick and flux-core, and swapping a liner or contact tip without calling someone over. Shops screen for this because a welder who can't tune the machine burns through wire and rework.

Reading weld symbols on a printKnowing which side of the reference line means arrow side, what the flag means for a field weld, and how to read a fillet size and length off the tail. You'll get asked to read one at the table before anyone hands you a stinger.

Prep work: grinding, beveling and cuttingA clean bevel from a flap disc, a square cut on the bandsaw, a straight line with a plasma torch or an oxy-fuel rig. New hires do this work most, so doing it tidily gets you in.

Step two

Gets you the offer

Fit-up and tacking to toleranceSetting root gap and landing, squaring parts with a framing square and clamps, and tacking in an order that keeps the joint from walking. A lot of failed booth tests start with a sloppy fit-up, not a bad bead.

Out-of-position weldingVertical up and overhead separate hireable welders from the rest. Practice uphill fillets and overhead stick until the puddle stops sagging.

Spotting and fixing your own defectsRecognising porosity, cold lap, undercut and slag inclusions before an inspector does, and knowing the likely cause of each. Explaining that your gas flow was off, and how you fixed it, sounds like someone who can work alone.

Fume, fire and shop safety habitsPositioning the fume arm, doing a fire watch around cardboard or oil, and checking hoses and regulators on an oxy-fuel setup. Supervisors notice who does this unprompted.

Step three

Gets you promoted

TIG on stainless and aluminumGTAW with a foot pedal, back purging stainless, and AC balance on aluminum. It takes the longest to learn, and it's what moves you onto the precision, food-grade and custom jobs most shops save for their best people.

Controlling distortion on big weldmentsPlanning a weld sequence, using backstep and skip welding, and pre-setting parts so a long frame comes out straight. Leads get picked for knowing how to keep a job from pulling out of square.

Working to a WPS and a codeReading a welding procedure specification, and knowing which code the shop builds to, such as structural steel or pressure piping. That knowledge is what turns a welder into a lead or inspector.

Layout and fabrication from full drawingsBuilding a cut list from a drawing, laying out holes and angles on raw stock, and deciding the build order yourself.

Certificates worth your time

Certificate	Best for	Effort	Worth it?
AWS Certified Welder	Anyone who wants proof on paper of a specific process and position before the shop test	A few weeks of practice on the exact test joint, then one test day at an accredited facility	The certificate foremen recognise most. It covers one process, position and material at a time, so test in whatever the local shops run.
AWS Certified Welding Inspector (CWI)	Experienced welders who want to move into inspection or quality roles	Several months of study for a hard, multi-part exam, and it expects real work experience first	A serious step up rather than a starter credential. Worth it once you're tired of the booth and know codes well.
NCCER Welding credential	Students in a school or employer program that teaches the NCCER curriculum	Earned through the course modules and performance tests, usually a term or longer	Useful on construction and industrial jobs that know the name. Not worth chasing on its own.

Test fees, renewal rules and accepted test facilities change, so check with the American Welding Society, NCCER or your training center before you book.

Questions people ask

What welding skill should I practice first?

Machine setup and flat fillets with MIG on mild steel. Once you can set voltage and wire speed by ear and lay a consistent bead, move to stick in vertical up. Those two cover most first jobs.

Is TIG worth learning if I'm new?

Learn it after you're solid on MIG and stick, not before. TIG is slow to pick up and most entry jobs don't use it. Later, it opens precision and stainless work.

How do I get better at reading prints without a job?

Get a weld symbol chart and a set of sample drawings from a welding textbook or your program, and practice explaining each symbol out loud.

Which skills move a welder toward inspector or lead?

Reading and working to a WPS, knowing your shop's code, controlling distortion on big parts, and building from full drawings. The CWI exam comes after you have the experience, not instead of it.
