MATERIAL - COBALT BASE ALLOY - L-605 SPOT WELD STRENGTHS (AN ABSTRACT REPORT)

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.
