ON THE WELDABILITY OF HIGH STRENGTH CAST STEEL COUPLER

Weldabilities of three 60 kg/mm square-class high strength steels newly developed as materials for fabrication of couplers (C 0.13 to approximately 0.29 percent, and small amounts of Ni, Cr, Mo, W, V, Cu, as well as Mn, Si) were investigated using the synthetic apparatus for weld thermal cycle. The relations between the results of investigation, the properties of buildup weld on couplers, and the crack-sensitivity of test steels were studied. Among the three steels, one with less carbon content (0.47 percent carbon equivalent) was better weldable and one with more carbon content (0.56 percent carbon equivalent) developed cracks in weld; the other was found unfit for buildup weld at atmospheric temperature. The results of experiments contributed to formulation of SCC 60 specification and provided a guide to the tolerable number of buildups.
