Abstract : The report examines the important metallurgical factors that must be considered when planning and executing a repair weld. The implications of the effect of reapir welding on the more complex high-strength heat treatable alloys and heat-resistant alloys are described. The possible deleterious effects of repair welding in terms of the metallurgy are also covered. Then the specific considerations applicable to each of several base-metal systems are examined. The alloys covered include steels of all types, aluminum alloys, nickel-base alloys, and titanium alloys. Following sections on types of defects and welding metallurgy, a final section is devoted entirely to examples of repair welding problems which have been solved and studies made to determine the effect of reapir welding on the properties of weldments.
