Effect of Flux Composition of Self-shielded Hardfacing Flux-cored Wire on Spatter

Effects of flux compositions of self-shield hardfacing flux-cored wire such as rutile,fluoride,wollastonite,zircite and magnesia on spatter were studied by orthogonal experimental design,an optimal mixture ratio of varied flux powders for nitride alloyed self-shield hardfacing flux-cored wire was got.With increasing contents of fluoride and zircite in the flux,the spatter increase.But with increasing contents of rutile,wollastonite and magnesia,the spatter decrease.When the flux contained 8.0%of rutile,4.0% of fluoride,4.0% of zircite,50% of magnesi and 2.0% of wollastonite,the welding process properties are optimal.
