Finish and repair:
The surface of the welded stainless steel tube must be clean and free of scale and contaminating iron particles. It can be bright annealed but may be pickled, blasted or can be passivated.
Repair by welding. Permitted on <−20% of the weld seam length of welded stainless steel tube if >−NPS 6 and having a wall thickness >−0.200 in (mm). Tungsten-arc welding process is used for repairs, with filler metal to a grade as specified in A 312 (not repeated here). Weld repairs must be identified on the pipe and in test certificate.
