Abstract
The welding of alloy steels is treated under three general headings; the low-alloy steels for general structural purposes, the heat-treated steels of the automotive type for machines and general engineering, and the high-alloy steels, such as stainless, for use in the chemical industries and the like. The effect of welding heat on metal adjacent to the weld proper and the intensity of internal stresses to be expected with joints of various design and various welding practices are discussed. It is shown that the butt weld has definite advantages from the engineering standpoint. The welding of heat-treated steels with austenitic welding rod and the welding of stainless steels with columbium-bearing welding rod are recent developments of note.
