Test results indicate that repair welding will increase the width of the heat-affected zone. The increased width results in lower design allowables for the welded joint than in straight welding. The average tensile strength of the repaired Set 1 specimens is higher than the original straight specimens. A probable explanation is that the severely induced stresses on the original specimens may have been reduced during repair welding. As in previous welding tests, the results are inconsistent. This is largely attributed to operator variables. Author
