Verify the protecting gas and change are as advised in the WPS. Reviewing sequencing procedures for distortion control. Tack weld high quality evaluation. Confirming a correct fit-up prior to welding. Inspecting the root pass and successive weld passes. Checking the root condition before welding the various other side. Making certain that slag, silica, and other contaminants are removed between passes.
