An analytical program has been started to determine the cause of cracking in DOP-26 iridium alloy during welding of GPHS clad vent sets. Analyses revealed that (1) intergranular cracking in the interior weld bead occurs in the heat-affected zone adjacent to the arc quench taper and at weld edges, (2) grain surfaces exposed by cracking exhibit a characteristic ridge network topography, and (3) no elements that could cause hot shortness were detected in the ridge networks.
