4.4.2.2 Potential inspector actions: • Require additional NDE to address deficiencies in findings. • Checking for delayed cracking of thick section, highly constrained and high strength material joining. • Repeat missing or unacceptable examinations. • Correct discrepancies in examination records.
4.4.3 Post-weld Heat Treatment Verify post-weld heat treatment is performed to the procedure and produces acceptable results. 4.4.3.1 Quality control items to assess: a. Paint marking and other detrimental contamination removed. b. Temporary attachments removed. c. Machined surfaces protected from oxidation. d. Equipment internals, such as valve internals, removed to prevent damage. e. Equipment supported to prevent distortion. f. Thermocouples fastened properly. g. Thermocouples adequately monitor the different temperature zones and thickest/thinnest parts in the fabrication.
