Abstract
In order to meet requirements of hot forge mould in the plastic manufacturing fields, the gas metal arc welding (GMAW) with a longitudinal electromagnetic field (LMF-GMAW) is applied to manufacture the bimetal thermal forming mould and repair the old die. The microstructure and mechanical properties are analyzed by SEM, EDS, micro-hardness, wear-resistance and thermal physical simulation testing methods. Our study shows that the LMF-GMAW method can increase the wear resistance property of the surfacing layer, enhance the interface bonding ability and improve the thermal mechanical strength of bimetal overlay work pieces.
