Worth establishing which before you accept.

What you'll be running

This posting calls for Flux-Core. 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

  • 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.
  • 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.
