Built-up Welding
The Advance of EBARA Surfacing Technology
Cold metal transition
CMT welding machine adopts cold metal transfer principle to surfacing, and the heat produced by CMT welding machine is only half of that of common surfacing machine, which can effectively slow down the failure rate of 625 alloy.
Wide range of surfacing
CMT welding machine can achieve three kinds of thicknesses, 1.6mm, 2.0mm and 2.5mm by only one layer of overlaying welding, and the Fe dilution rate can be controlled within 5%.
Good surfacing quality
Ordinary welding machine (pulse MIG) can control the dilution rate of Fe on the surface layer within 5% with two layers of surfacing. As the dilution rate of the two layers is discontinuous, once the corrosion breaks through the surface layer, the corrosion rate of the inner layer will increase exponentially, thus affecting the service life of the whole surfacing layer; while the CMT surfacing process adopted by our company is far more advanced than the ordinary surfacing process, and the dilution rate of Fe can be controlled within 5% only by one layer, and the dilution rate from the surfacing layer to the base metal is continuous, the corrosion rate is constant, and the service life of the surfacing layer is effectively guaranteed.
Slow thinning rate
According to the inspection data of the surfacing surface of Japanese customers, CMT surfacing process is adopted, which is mature and reliable, and the thinning rate is very low. The thinning is about 0.05mm/year.
Unique CMT single-layer surfacing process, the service life reaches the industrial flat top level
