Fast reactor irradiated AISI 304L stainless steel tubing was fusion-welded using conventional inert gas-tungsten arc welding (GTAW) procedures which were adapted for remote operation. Metallographic examination of weld joints sometimes revealed porosity in the weld zone and cracks at the tube inner wall within the heat-affected zone. A stress analysis was performed to evaluate these defects as sites for weld failure and to establish procedures for the detection and rejection of weld joints likely to fail in service.
