Product introduction:

Surfacing repair workpiece: single-tooth roller

Welding wire model: TM643

Welding wire diameter: 1.2-1.6

Welding method: gas shielding


Recommended Wire Welding Wire and Features:

TM643 is CO2 or 80%Ar+20%CO2 protected wear-resistant surfacing flux-cored wire. The surfacing welding wire has excellent welding performance, beautiful shape and small spatter. The deposited metal is a high-chromium alloy, so it has excellent wear properties of wear-resistant materials. At the same time, Mo, W, V, B and other elements are added to improve the high temperature wear resistance of the weld metal, and Ni element is added to ensure that the weld increases the impact resistance without reducing the wear resistance. 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:

It is used for surfacing workpieces subjected to strong abrasive wear at high temperature, such as single-toothed rollers, grate plates, distribution chutes, etc.


Surfacing process:

1. Before surfacing welding, remove the oil, rust and other dirt on the surface of the workpiece to be welded, and remove the fatigue layer.

2. It is best to preheat the base metal before welding, the temperature should be above 250 degrees, and the temperature should be kept warm and cooled slowly after welding.
