At roughly $103/hr, this posting sits about 314% above the $25/hr median for welding jobs in Houston, TX — toward the top of a $22–$32/hr middle band drawn from 76 postings with published pay. Put another way, it pays more than about 100% of the comparable postings we have wage data for.

Worth establishing which before you accept.

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.

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.
