Neither preheating nor post-weld heat treatment are generally required.
GTAW orPAW should not be done without a filler metal unless post-weld cleanup is possible.
It does not require post-weld annealing and so is extensively used in heavy gauge components(over about 6mm).
Grade 420 coated welding rods are recommended for high strength joints,where a post-weld hardening and tempering heat treatment is to be carried out.
If the weldment cannot be post-weld heat treated, the flat welded flange pipe welding rod(A107, A207) should be used.
If welding is to be done on only one surface and post-weld cleaning is not possible, GTAW is suggested for root passes.
Fittings in all thicknesses produced by fusion welding after the heat treatment specified in 1 shall be post-weld heat treated at a temperature not less than prescribed above for tempering except that Grade WP1 is required to be post-weld heat treated only when the nominal wall thickness at the welded joint is 1⁄2 in.[13 mm] or greater, and except that preheat and post weld heat treatment are not required for WP24 fittings whose section thickness does not exceed 0.500 in.[12.7 mm].
This skin effect produces higher weld speeds,hence post-weld heat treatment is not considered necessary because of the superficial nature of the changes in the microstructure.
