Pay in context

At roughly $87/hr, this posting sits about 190% above the $30/hr median for welding jobs in Phoenix, AZ — toward the top of a $23–$39/hr middle band drawn from 91 postings with published pay. Put another way, it pays more than about 100% 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.

Certifications this posting mentions

  • 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.
  • 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.
