Description

Technical field [0001] The invention relates to the technical field of soldering, in particular to a pressure soldering device and a soldering method under the protection of inert gas in a furnace. Background technique [0002] The existing soldering technology is mainly to hang the formed superconducting cable and the inner hole of the copper head of the splitter with tin respectively, and complete the assembly of the superconducting cable and the copper head at room temperature, and heat the superconducting cable and the copper head by heating tooling to reach a predetermined temperature. Add tin to the assembly gap between the guide cable and the inner hole of the copper head to complete the soldering of the superconducting cable and the inner hole of the copper head. The disadvantage of this method is that the cold assembly has a low success rate and is easy to damage the superconducting cable. There is no gas protection during the welding process, and the workpiece is prone ...
