摘要：

Tungsten inert gas arc welding of WC - 30 wt-% Co cemented carbide and steel was carried out using a variety of filler alloys. Precipitation of Fe3W3C occurred at the joint interface and this reduced the bend strength and toughness of the welded joint. The problem could be alleviated by adjusting the carbon concentration of the filler metal.
