    During the entire surfacing process, attention should be paid to the surfacing temperature and surfacing time. If the temperature is too high or the welding time is too long, it will cause the casting wc particles to melt, the quality of the surfacing layer to deteriorate, peeling off and the generation of pores. In addition, if the temperature is too high, the deposited Wc particles will be deposited, and the surface iron will be excessive, which will affect the wear resistance of the surfacing layer. However, if the temperature is too low, the fluidity of the melt is lowered, the surface of the weld overlay layer is uneven, and the joint strength between the weld overlay layer and the base metal is also lowered. Under normal circumstances, the penetration depth of the base metal should not be too large, the temperature must be suitable, the welding time is as short as possible, and the cooling rate is slow. more contact sales-manager202@wococarbide.com
