Upset welding process for 21-6-9 spherical vessels

Technical Report ·

This report discusses an upset resistance welding process which was developed to fabricate high quality spherical vessels from forged 21-6-9 stainless steel. The two hemishells of the vessels were joined at the girth using solid-state upset welding. Vessels passed nondestructive examinations (X-ray radiography, proof and leak tests, volume and dimensional measurements) and destructive examinations (burst tests and metallography). A set of six high quality vessels was produced. These vessels are 1.86 inches in diameter with a threaded boss and tube on top.
