________ and _______ damage develop without applied or residual stress so that PWHT will not prevent them from occurring.
________ and _______ damage develop without applied or residual stress so that PWHT will not prevent them from occurring.
Blistering and Hydrogen Induced Cracking (HIC) damage develop without applied or residual stress. Post Weld Heat Treatment (PWHT) is not effective in preventing these forms of damage because they occur due to hydrogen not due to stress.
