Abstract

The invention discloses a high-frequency electric heating welding device, which comprises a high-frequency electric heating welding machine and a welded pipe support, wherein the high-frequency electric heating welding machine is provided with an induction coil; a lifting mechanism is arranged on the welded pipe support; a fixed die is arranged on the lifting mechanism; a welded pipe is fixed in the fixed die; and the welding part of the welded pipe is arranged in the induction coil to be heated. Compared with the prior art, the high-frequency electric heating welding device has the advantages that: the conventional welding mode is replaced by an electric heating mode of a copper pipe, so that the production cost can be saved, the device is safe and environment-friendly and easy to operate, dependence on labor is reduced, and the welding efficiency is improved.

Description

technical field [0001] The invention relates to the field of welding equipment, specifically a high-frequency electric heating welding device. Background technique [0002] At present, in order to save the cost of raw materials, steel pipes, iron pipes or brass pipes are generally used to replace part of the copper pipes for the inlet and outlet pipes of the liquid receiver or separator. Types: 1. Brazing furnace welding; use electric power (90kw / hour for the production equipment of the conventional liquid storage device of the brazing furnace), ammonia gas, oxygen, cooling water, silver welding ring, and apply flux for welding; 2. Flame welding: use Oxygen, acetylene or propane, liquefied gas, copper wire, flux for soldering. The above two welding methods have defects such as high cost, high pollution, unenvironmental protection, low efficiency, and great dependence on welders. Contents of the invention [0003] In view of the above defects, the technical problem to be ...
