basic information
• A plasma arc welding method that enables the cladding of various hard carbides and composite alloys, which have traditionally been difficult to weld. • Similar to TIG welding, an arc is generated from a non-consumable tungsten electrode, and filler material is supplied from the outside into the arc to proceed with the welding. • A significant feature is that the welding material is in powder form, which has the following advantages: 1. Cladding welding of original filler materials is easy with a blend of various material powders. 2. Welding is possible for hard and brittle materials, such as composite alloys of carbides and metals, which are difficult to shape into welding material forms like wires or rods.
