Hardfacing Surfacing Flux Core Wires For Coal Mining Bits
Surfacing repair workpiece: coal pick / Coal mining bits
Welding wire model: TM605
Welding wire diameter: 1.2-1.6
Welding method: gas shielding
Welding wire features:
TM605 flux-cored wire is CO2 or 80%Ar+20%CO2 protected wear-resistant surfacing flux-cored wire. The gas shielded flux-cored welding wire has excellent welding performance, beautiful shape, less spatter, and the welding efficiency is more than 3 times that of the manual electrode. The deposited metal is high-chromium alloy, and the metallographic structure is martensite plus alloy carbide. Because the carbide has extremely high hardness, it has excellent wear resistance of wear-resistant materials. When the wire is surfacing, fine cracks will appear, which is the result of stress release, and will not affect the normal use under low-impact industrial and mining conditions.
Scope of application:
Single or multi-layer surfacing welding of worn parts, such as buckets, mining machinery, etc.
Surfacing process:
1. Remove the oil, rust and other dirt on the surface of the workpiece before welding, and avoid using excessive voltage during welding to prevent the occurrence of pores.
2. Remove welding slag between welding layers, and pay attention to avoid slag inclusion.
It is best to preheat the base metal before welding, and the temperature should be above 250 degrees.
