How this job compares in West Rancho Dominguez, CA

Pay in context

At roughly $45/hr, this posting sits about 32% above the $34/hr median for welding jobs across California — toward the top of a $28–$43/hr middle band drawn from 428 postings with published pay. Put another way, it pays more than about 76% of the comparable postings we have wage data for. Pay that far above local median usually comes attached to something: a harder cert requirement, travel, night shift, or overtime that isn't really optional. Worth establishing which before you accept.

What you'll be running

This posting calls for MIG, TIG, Stick, and Flux-Core 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.
  • CWI — the AWS Certified Welding Inspector credential. It is an inspection qualification rather than a welding one, requiring documented experience plus a three-part exam, and it is the usual route off the torch into QC.

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.
