Repair by Welding
1 For welded pipe whose diameter equals or exceeds NPS 6, and whose nominal wall thickness equals or exceeds 0.200, it is permitted to make weld repairs to the weld seamwith the addition of compatible filler metal using the same procedures specified for plate defects in the section on Repair by Welding of Specification A999/A999M.
2 Weld repairs of the weld seam shall not exceed 20 % of
the seam length.
3 Weld repairs shall be made only with the gas tungsten- arc welding process using the same classification of bare fillerrod qualified to the most currentAWS SpecificationA5.9 as the
grade of stainless steel pipe being repaired and as shown inTable 6. Alternatively, subject to approval by the purchaser,weld repairs shall be made only with the gas tungsten-arc
welding process using a filler metal more highly alloyed than the base metal when needed for corrosion resistance or other properties.
4 Pipes that have had weld seam repairs with filler metal shall be uniquely identified and shall be so stated and identified on the certificate of tests. When filler metal other than that listed in Table 6 is used, the filler metal shall be identified on the certificate of tests.
