What you'll be running

This posting calls for Stick and Flux-Core work. 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. Flux-cored (FCAW) runs a hollow wire filled with flux, combining MIG-like deposition rates with the outdoor tolerance of stick. It is the workhorse on heavy structural steel and shipbuilding, where thick sections and long welds reward speed.

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.
  • 3G / 4G — plate position tests — 3G is welded vertically, 4G overhead. Together they demonstrate you can hold a puddle against gravity, and they are the common entry qualifications for structural and production shops.

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.
