Abstract

The invention belongs to the technical field of welding and relates to a copper bus electric heating device and a use method. The invention relates to a copper bus electric heating device, which comprises two clamping boxes, heat-insulating cotton, electric heating sheets, and several clamping pieces for making two clamping cases close and fit together, which are arranged in sequence. The thickness of the heat-insulating cotton is uniformly fixed in the cavity of the clamping box, and the electric heating sheet is fixed on the outside of the heat-insulating cotton for contacting with the copper bus for heating. In that device, the problem that the traditional electric heat method is low in construction efficiency and easy to cause damage to the insulation sleeve is avoided, the heat is uniform, and it is easy to make and use.

Description

technical field [0001] The invention relates to a copper busbar electric heating device and a method for using the device, and belongs to the field of welding technology. Background technique [0002] Copper busbar is a conductor that transmits high current. Due to the high thermal conductivity of copper, which is about 8 times higher than that of ordinary steel, the heat dissipation is rapid during the welding process, and the base metal is difficult to melt and not easy to fuse with the weld metal, resulting in easy welding. In case of quality defects such as lack of fusion, porosity, welding deformation, and cracks, measures such as preheating and increasing the power of the welding heat source must be adopted to ensure the quality of the weld. Preheating methods are generally flame heating and electric heating. [0003] The electric heating method, that is, using electric heating sheets for heating, using thermal insulation cotton to keep warm, and using thermocouples ...
