Two weldability tests developed by ORNL for plate material have been demonstrated on iridium (Goodwin 1987 and David 1987), but neither test is applicable to underbead cracking in a capsule configuration. As a result of underbead cracking of welded iridium capsules at SRP, a weldability test was designed and demonstrated on capsules to measure the susceptibility of different batches of iridium to underbead cracking. The capsule weldability test and its use to determine the relative weldability of the ORNL new-process iridium is presented in this paper. 6 refs., 1 fig., 1 tab.
