Abstract

Solidification crack susceptibility in partially-melted bead-on-plate laser beam weld metal of 6mm thick 0.2C-1.8Ni-0.55Cr-0.25Mo low alloy steel has been investigated with change of S and P content using a max. 5KW laser beam welder. Effects of weld bead configuration and amount of S and P on crack length in crosssectional bead have been mainly investigated. Estimation of crack length in weld metal was tried by means of regression analysis of data, using bead configuration and S and P. Moreover effect of restraint of weld bead during welding on crack susceptibility was investigated.
