Hot cracking of austenitic stainless steels: the debut of the Sigmajig
Conference
·
OSTI ID:5846267
The Sigmajig test fixture holds a square specimen between grips and applies a stress prior to welding. An autogenous weld is then produced. As the stress is increased specimen by specimen, a level is reached where centerline cracking occurs near the end of the weld. At a higher stress level, specimen separation occurs. Testing has concentrated on gas tungsten arc welds on 0.25 mm thick types 304 and 316 stainless steel. Scanning electron microscopy examination confirms that the centerline cracks are indeed hot cracks. (LEW)
