Some of the common quality control checks during welding are: Verification of pre-heat and interpass temperature levels and making certain that they are within limits defined in the WPS.

Validate the shielding gas and flux are as advised in the WPS. Examining sequencing procedures for distortion control. Tack weld quality evaluation. Confirming a correct fit-up prior to welding. Evaluating the origin pass and succeeding weld passes. Examining the origin problem prior to welding the opposite side. Ensuring that slag, silica, and various other contaminants are removed between passes.
