AWS ASME IX Endorsement case studies
AWS ASME IX Endorsement · Put your knowledge to work in context.
The ASME BPVC Section IX endorsement is an add-on credential offered within the AWS CWI and SCWI Endorsements program - that is, it is earned on top of an existing Certified Welding Inspector or Senior Certified Welding Inspector credential rather than as a stand-alone certification. AWS lists it alongside endorsements such as Structural Steel (D1.1), Bridge Welding (D1.5), Pipeline (API 1104) and ISO Standards, which tells you the intent: it certifies that an inspector can work competently against a specific code family rather than only against general welding inspection fundamentals. The AWS ASME IX Endorsement case studies are 5 cases and about 3,303 words.

A shop's BPS-1, supported by BPQR-1, covers furnace brazing of C12200 copper tube to 304L stainless tube in a hydrogen atmosphere: BAg-1a paste filler, 1500 °F, 10 minutes at temperature, joint clearance 0.002–0.004 in, qualified on 3/4 in OD × 0.065 in wall tube, with visual and sectioned test specimens. The BPS as issued lists brazing temperature "1450 °F–1600 °F" and clearance "as required." A new product line uses the same two base metals but requires: (1) vacuum furnace brazing at 10⁻⁴ torr; (2) 1560 °F with 25 minutes at temperature to soak larger assemblies; (3) BAg-1a paste from a different supplier; (4) joints with 0.005–0.008 in clearance; and (5) a redesigned fixture.
