| description | The invention discloses a welding technology for a copper pipe and a steel pipe. The copper pipe and the steel pipe are circular pipes. The technology comprises the steps that (1) the copper pipe and the steel pipe which are in insertion connection or butt connection are integrally fixed to a clamp body rotating on a machine tool at a constant speed; (2) the current of an argon arc welding gun is adjusted, the electric arc heating temperature of the argon arc welding gun is made to reach more than 1000 DEG C, the angle of the argon arc welding gun is adjusted, and the argon arc welding gun is made to be aligned with the portion where the copper pipe is combined with the steel pipe; (3) the argon arc welding gun is started to heat the circumference of the portion where the copper pipe is combined with the steel pipe when the copper pipe and the steel pipe rotate at the constant speed, after heating for 5 s, copper at the portion where the copper pipe is combined with the steel pipe is in the molten state, and |
