Study on Microstructure and Corrosion Behavior of Laser Weld between YG20 Cemented Carbide and 45~# Steel AITranslate
Abstract AITranslate
Laser welding of 45#steel to 4mm thick YG20 cemented carbide was achieved with 5kW fiber laser as the heat source.Distribution characteristics of weld microstructure were analyzed,and surface morphology was observed of the weld etched in HNO3,H2O2 and Murakami reagent,respectively.And then the influence was discussed of laser scanning speed on weld formation between dissimilar metals with relatively large thermal expansion coefficient difference.The results indicate that when welding materials are 4mm thick,YG20/45#steel welded joint with excellent metallurgical bond can be obtained under the conditions of 3.84 kW laser power,0.96m/min laser scanning speed and-8mm defocusing amount.
