FCAW Welding Hardfacing
FCAW Welding Hardfacing is a kind of welding which can produce self-protective gas after the flux cored and the welded parts produce arc. The welding wire is fused to a flat plate or a roller at high temperature, which is a kind of welding method.
Principle and characteristics:
Due to the effect of the cladding process, which uses rapid cooling and refinement of crystals such as chromium carbide, it is possible to reduce costs. The cladding layer has excellent wear resistance and does not require the use of solvents, thus reducing costs.
Use of 1.6-3.2 mm diameter self-protecting flux cored wire.
- Compared with submerged arc welding, open-arc welding has significant advantages, so it has been widely used.
- The use of self-shielded flux cored wire, no welding slag generated, without adding flux
- No preheating before welding, no heat treatment after welding, high welding efficiency and energy saving.
