What you'll be running

This posting calls for TIG and Stick 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. Stick (SMAW) burns a flux-coated consumable rod and needs no shielding gas, so it works in wind, rain, and on dirty or rusted steel. That tolerance for bad conditions keeps it the default for field, structural, and repair work.

Certifications this posting mentions

  • 6G — a pipe test welded on a joint fixed at a 45-degree incline. Because the torch has to travel through flat, vertical, and overhead angles in a single pass, passing 6G qualifies you for every position on pipe — which is why it is the ticket that separates pipe welders from plate welders on pay.
  • AWS D1.1 — the American Welding Society's Structural Welding Code for steel. It governs almost all building and structural steel work in the US, so a D1.1 qualification is the baseline credential for construction and ironworking.
  • 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.
