Abstract

The invention relates to a welding device and a method; the welding device comprises a current-limiting resistor (1), a fixed clamp (2), a moving clamp (3), a capacitor (9) and a power supply and control system (10), wherein the power supply and control system (10) is connected with the current-limiting resistor (1) and the capacitor (9) so as to form a circuit; the capacitor (9) is connected with the fixed clamp (2) and the moving clamp (3) so as to from a circuit; a first welding piece (4) is clamped in the fixed clamp (2); and a second welding piece (41) is clamped in the moving clamp (3) and is connected with a position adjusting device (A) which is connected with a spring (6) and is provided with a clamping device (5). When in welding, the moving clamp (3) is pulled toward right and is hooked by the clamping device (5); the power supply is powered on and when the capacitor (9) is charged to working voltage, the clamping device (5) is released. The invention has simple welding device, convenient operation, high welding joint strength, corrosion resistance and high welding efficiency.

Description

technical field [0001] The invention relates to welding technology, in particular to a welding device and method for copper tubes and aluminum tubes, aluminum tubes and aluminum tubes, and copper tubes and copper tubes. Background technique [0002] At present, the welding technology of copper tube and aluminum tube, aluminum tube and aluminum tube, copper tube and copper tube mainly includes: brazing, friction welding, energy storage welding and resistance welding. Brazing is a welding method that uses a metal material with a lower melting point than the base metal as the solder, wets the base metal with liquid solder and fills the gap between the workpiece interface and makes it diffuse with the base metal. On September 28, 1988, the Chinese Patent Office 88105479 discloses a socket brazing method for aluminum-copper conduits, which uses aluminum silicide and potassium fluoroaluminate crystal stone as solder and flux, and coats the intermediate layer on the weldment before...
