METHOD TO DETERMINE POST-WELD HEAT TREATMENT REQUIREMENTS FOR EXTERNAL WELDED ATTACHMENT TO AVOID ENVIRONMENTAL STRESS CORROSION CRACKING

A method is provided for determining whether post-weld heat treatments should be required for external attachment welds in applications where stress corrosion cracking is a possibility. According to the method, residual stress values are measured in test samples welded at high input heat levels and...
