Özet
In this study, the weldability of wear resistant hardox steel to austenitic stainless steel with shielded metal arc welding (SMAW) and gas metal arc welding (GMAW) methods was investigated and an effect of welding method on the mechanical properties and microstructure of weldment was examined. According to standard, welding groove was prepared for Hardox 400-AISI 304 steel couple that was multi pass welded in butt position by using GMAW and SMAW methods. The mechanical properties of the weldments were determined by tensile, three point bending and V-notch impact tests. In addition, hardness measurement and microstructure evaluation was carried out on the cross section of weldment. According to findings; the tensile strength, weld metal notch impact toughness and ductility of the samples joined with the GMAW method were determined higher than those joined with SMAW.
