The Numerical Analysis And Experimental Study On Plasma Arc Welding Of Copper Alloy

It is a problem for welding when there are requirements on the temperature field of high thermal conductivity alloy welding . In this paper, In this paper, copper alloy as an example of a high thermal conductivity, such as plasma arc welding of the pilot study. And to separate the copper alloy laser welding, tungsten argon arc (TIG) welding, Comparison of three methods of welding temperature field width.Plasma Arc Welding (PAW) is the main method of high energy density welding share a wide range of areas . The issue of water and electricity through the separation of plasma arc welding torch to connect power control, such as plasma arc welding fixture circuit design at the same time, copper alloy and the plasma arc welding experiment in-depth study of its welding technology.In this paper, using finite element analysis software, high thermal conductivity alloy plasma arc welding temperature field a simulation study. Of copper alloy, such as plasma arc welding temperature field simulation and numerical analysis of the heat source model of a summary. A transition mesh, and copper alloy laser welding, TIG welding temperature field simulation, three welding method to compare the temperature field width.Through the above theoretical and practical aspects of analysis and study, the high-quality of welded joints on the topic at the same time meet the welding thermal field should not be too large requirements. Give full play to the plasma arc welding superiority more fully the actual use of plasma arc high temperature geothermal field energy density of small advantages.
