Arc Welding of High Speed Steel

Abstract

On a stand point of economical using, high speed steels have been welded to carbon steels by many kinds of welding methods such as solderings, electric flash wel-ding and other electric resistance weldings and also de-posit metal of high speed steel have been made on the carbon steel shank by atomic hydrogen welding method or oxyacetylene gas welding method.
This paper pointed out a fact that electric metallic arc welding with 18-8 stainless steel electrode was a most practical welding method for use in connection with high speed cutting tools of peculiar type to which other welding methods were not expedient. High speed steel and carbon steel can also be welded with ordinary mild steel electrode but cracks are apt to occur in the welding joint-commonly in high speed steel side-caused by the formation of carbides and blow holes in deposit and by the hardening of heat affected region of base metal adjacent to deposit.
It is considered that easy melting of 18-8 stainless steel electrode and desirable toughness of its deposit are enable to get rid of these crack failures of weld.
