Applications / Features
Flexible, pliable welding rod, manufactured as a composite, in various sizes of spherical fused tungsten carbide (WSC). The welding rod has a very high matrix and scratch hardness and is used for hard surfacing deposits on components subject to extremely fine mineral wear.
The workpiece surface must be free of scale, rust, oil and grease and free of old loose residues and contamination. In the area of hardfacing, a uniform preheat of 300°C – 350°C throughout the cross-section must be ensured. In the hardfacing area, the component surface temperature should be approx. 650°C at the start of hard overlay welding.
Applications
Suitable for hardfacing on: Tools and attachments used in soil, rock and earth applications, in mining, open-pit mining and tunneling, and in the foundry, forging,ng-,ng, steel, iron, metallurgy, glass, brick and refractory industries.
Typical components:
Screw presses, separators, decanters, screw segments, screw tools, conveyor screws, impact bars, cutting edges, cutting heads, knives, scrapers, mandrels, ploughshare mixers, armour welding of crowns, drill crowns, deep drill bits, round shank chisels, coal ploughs, cutting machines, moulded cores, pan mixers, mixing paddles, mixing tools, mouthpieces, profile borers and excavator teeth
