通过理论分析和焊接试验研究了Ｌ１３５硬质合金与６５４２＃高速钢、ＹＧ类硬质合金与４５＃钢的激光焊接。用扫描电子显微镜、电子探针分析仪、弯曲强度测试仪对焊接试样进行微观结构和宏观应力分析，通过试验得到了硬质合金与钢冶金结合的激光焊接试样。
The laser welding of L135 cemented carbide with 6542 # high speed steel, YG cemented carbide and 45 # steel was studied by theoretical analysis and welding experiment. The microstructure and macroscopic stress of welded specimens were analyzed by scanning electron microscope, electron probe analyzer and bending strength tester. The laser welding specimens were obtained by the experiment.
