Metal backing may be used when permitted by project specifications. Backing materials shall consist of the same P number as the base material. When using split-type backing rings in pipe, tack welding across the split is not permitted. Backing rings in pipe and tube shall be securely tacked on the upstream side of the joint to prevent dislodgement in service.

Remove oil, grease and other contaminants using approved solvents. Method of Backgouging: For double-welded joints, back-gouge to sound weld metal using mechanical or thermal methods before welding second side. Interpass Cleaning: Chip, file, grind and/or brush each layer as needed. Inspect and remove defects prior to depositing next pass. Final Cleaning: Chip and wire brush. Note 4:
Use an adequate amount of filler metal and avoid concave root deposits which could cause center-line cracking because of the thermal contraction characteristics of the Inconel fillet metal.
