Ultrasonic inspectability improvements of austenitic stainless steel welds after thermal-mechanical processing
Conference

OSTI ID:5188928
A thermal-mechanical process was applied to Type 304/308 stainless steel GTA welds. The process improved the ultrasonic transmission properties in the weld region. These improvements are attributed to the microstructural changes observed after processing of the austentitic stainless steel welds. Some of the microstructural changes observed were conversion of cast dendrites into equiaxed austenitic grains, and the reduction in size and number of stringers, inclusions, and delta ferrite.
