Welding device

Abstract

The invention discloses a welding device. The welding device comprises a high-frequency device, a first coil segment and a second coil segment. The first coil segment and the second coil segment are oppositely arranged, and the relative position of the first coil segment and the second coil segment can be adjusted so that a matching state of the first coil segment and the second coil segment and a separating state of the first coil segment and the second coil segment can be switched. When the first coil segment and the second coil segment are in the matching state, a first end of the first coil segment and a first end of the second coil segment are electrically connected with the high-frequency device respectively; the first end of the first coil segment is close to the first end of the second coil segment, a second end of the first coil segment makes contact with a second end of the second coil segment, so that an annular coil is formed by the first coil segment and the second coil segment. When the first coil segment and second coil segment are in the separating state, the second end of the first coil segment is separated from the second end of the second coil segment. The welding device can be used for welding air suction pipes, air cylinder connecting pipes and liquid accumulator elbows, and is short in welding time and high in welding efficiency.

Description

technical field [0001] The invention relates to a welding device. Background technique [0002] The suction pipe of the compressor, the connecting pipe of the cylinder and the elbow pipe of the liquid receiver are generally fixed by welding. At present, the flame brazing process is mostly used in the industry. However, flame brazing will produce strong light, a lot of heat and noise, which will affect the health of welders and cause some pollution to the environment. Moreover, the flame brazing process requires the laying of a large number of pipes and valves in the workshop, and the gas required for flame brazing is flammable and explosive, posing potential safety hazards. In addition, flame brazing requires high welding skills for welders and requires mature flame brazing technicians.

AI Technical Summary

Problems solved by technology

However, flame brazing will produce strong light, a lot of heat and noise, which will affect the health of welding workers and cause some pollution to the environment.

Moreover, using the flame brazing process, a large number of pipes and valves need to be laid in the workshop. At the same time, the gas required for flame brazing is flammable and explosive, posing safety hazards

In addition, flame brazing requires high welding skills for welders and requires mature flame brazing technicians

[0003] In addition, there is another welding method using U-shaped electromagnetic coils, but when using U-shaped electromagnetic coils for welding, due to the uneven distribution of magnetic force lines, there is no magnetic force lines at the U-shaped opening, and the heat can only be slowly transferred to the opening of the U-shaped coil. Long heating time and low efficiency

However, O-shaped coils used in other fields cannot be welded due to interference with components such as the compressor liquid reservoir.
