What you'll be running

This posting calls for MIG, TIG, and Stick work. MIG (GMAW) feeds a continuous wire electrode through a shielding-gas nozzle. It lays down metal fast and is forgiving on clean material, which is why it dominates production and light fabrication work. TIG (GTAW) uses a non-consumable tungsten electrode with filler added by hand, giving the operator the most control of any process. It is slow, demanding, and the standard for stainless, aluminum, and anything where the bead has to look as good as it holds.

Certifications this posting mentions

  • ASME Section IX — the ASME Boiler and Pressure Vessel Code qualification. It covers welding on pressure-retaining equipment — boilers, vessels, and process piping — where a failed weld is a safety incident rather than a rework ticket.

Read straight from this posting's text. Confirm the exact qualification the employer wants before you test — requirements vary by shop even under the same code.
