Investigation of copper and copper alloy's welding and discussion on manual SHS welding of copper and copper alloy

Meaning of research on Copper and Copper Alloy’s welding is of great importance because of the good property and abroad application.Technical characteristics of Copper and Copper Alloy’s normal welding,like gas welding,brazing and soldering,activing welding,MIG welding,friction stir welding,thermit friction stir welding,laser welding,laser welding electron beam welding and Self-propagating High-temperature Synthesis(SHS) welding was studied and classified in the paper as well as the analysis about domestic and foreign present situation of research.It is also analyzed that how normal welding can provide direction and guidance for the Manual SHS Welding Technology of Copper and Copper Alloy.Moreover,the present problem of manual SHS welding of copper and copper alloy is discussed,especially the wettability between welding seam and base metal,the separation between slag and welding seam on emphasis,and the further research orientation was indicated.
