While not a "welding procedure" standard, it is the benchmark safety standard for welding and cutting, essential to work with ASME-certified shops. 6. Benefits of ASME Welding Certification Adhering to ASME standards offers significant advantages:
Whether you are a shop foreman, a project engineer, or a quality manager, investing time to fully understand ASME welding standards will save you from catastrophic failures, regulatory fines, and loss of license. When in doubt, consult the latest edition of —and remember: a weld is only as good as the standard it meets. Must be tested & backed by a PQR
