This study presents information on the use of consumable inserts to make 100% penetration welds in 304 and modified A286 (designated JBK-75) stainless steels. Current and voltage ranges which produced acceptable welds were found for different combinations of joint preparations and inserts. Three third member insert designs were examined: Type A (AWS Class 1), Type G (AWS Class 3), and Type K (AWS Class 5). One joint design incorporated the configuration of the Type G insert into the root face of the joint (termed an ''integral insert''). Joints welded with and without filler wire addition were made for comparison. Metallurgical and radiographic tests were done on all welds. It was found that the consumable insert root pass was comparable to the wire-fed root pass in weld shape and size using the same parameters; it also had additional advantages in ease of use, cleanliness, inspectability and reduced procedure complexity.
