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.
