Abstract:

Annealed, 0.031 in. and 0.050 in. thick, mill annealed 2250 F, water quench, L-605 Haynes Alloy No. 25, Haynes Stellite Co. was cleaned by the methods given and then spot welded. The 0.031 in. thick sheet was welded according to the schedule given, and the 0.050 in. thick according to the schedule. The results from tests with spot welds in mill-annealed and re-annealed 1975 F, 30 minutes, rapid air cool conditions are shown. These data show that spot weld strengths optimize when mill-annealed material is welded without subsequent heat treatment. Annealing 1975 F, 30 minutes, air cool generally reduces weld strengths, especially the cross-tension strength, and thus contributes to reductions in tension-shear to cross-tension strength ratios.
