Abstract

The laser molten welding of cemented carbides and steel is discussed in this paper. It presents the mechanism of dip soldering. The changes of material structure of welding seam, elements composition and the cause of fissures have been analyzed. The changes of tension of carbides and cobaltic phase in welding process are investigated. The effect of laser plasma on surface of specimen is discussed. The welding results of heterogenous materials between L135 cemented carbides and 6542 tool steel, YG15, YG12, YG8 cemented carbides and 45 steel are also discussed.
