Pay Attention to Dissimilar-Metal Welds

Abstract

Dissimilar - Metal welding refers to the joining of two different alloy systems. Actually all fusion welds are dissimilar-metal welds (DMWs) because the metals being joined have a wrought structure and the welds have a cast structure. Frequently the matching-composition filler metal is deliberately altered from that of the base alloys. For this Discussion a Dissimilar-metal Weld will be that between metals of two different alloy systems.
