【Abstract】 In this paper, a numerical analysis model for non-linearly welding thermo-field is set up. The finite differential technique is applied to calcula tion of the welding thermo-field of variable-section workpieces, and a computer program is designed. The functional relationship between the welding amperage and the coordinate value in the weding direction, i.e., an intelligence control model of variabe-section workpieces in TIG welding process is set up.更多还原
