An additional example would be not inspecting for too much distortion, which would lead to weld being rejected and expensive rework if done on pricey equipment like heat exchangers, distillation columns, and boilers. Several of the typical high quality control checks throughout welding are: Verification of pre-heat and interpass temperature levels and making certain that they are within limits defined in the WPS.


Confirm the securing gas and change are as advised in the WPS. Reviewing sequencing treatments for distortion control. Tack weld high quality assessment. Confirming an appropriate fit-up prior to welding. Inspecting the origin pass and successive weld passes. Examining the root condition prior to welding the other side. Ensuring that slag, silica, and other contaminants are gotten rid of in between passes.
