Riechman, A F

SRL and SRP completed a joint preliminary investigation in which acoustic emission (AE) was collected during the pinch welding of 304L S.S. tubes similar to those used for fill stems on D/T (deuterium/tritium) gas reservoirs. Attempts to correlate the AE data with welding variables and pinch weld strength have been made. This work was done as one element of SRL's Closure (Pinch Weld) Reliability Program. One of five main tasks of this program is to develop an NDE technique to determine pinch weld quality. The main objective is to demonstrate a nondestructive test which is suitable for production use that will ensure high-strength pinch welds.
