Paper Title:
Research on Cu-Fe Laser and Tungsten-Arc Inert-Gas Hybrid Welding
  Abstract

To achieve the welding of the larger copper substrate and iron parts, the new method of laser-TIG (Tungsten-arc Inert-Gas welding) hybrid welding is proposed. Experiment shows that the Ni-Cr alloy cladding layer is firstly prepared by YAG laser on the welding body of copper surface, it is metallurgically combined with copper substrate, and then the 5 mm diameter iron cylinder is welded by TIG welding in the cladding layer. The welding zone is fine, no weld cracks is observed under the microscope, metallographic analysis shows that copper and iron is the metallurgical bond.
