Copper sheet welding method using new auxiliary carrier

Abstract

The invention discloses a copper sheet welding method using a new auxiliary carrier. The copper sheet welding method comprises the following operation steps that a vacuum sintering method is adopted when copper sheets are welded, a proper steel material is found in a chromium-molybdenum steel system, chromium-molybdenum steel is selected as the welding auxiliary carrier, the chromium-molybdenum steel is alloy elements such as chromium, molybdenum, iron, carbon and the like, the copper sheets are welded through continuous high temperature under the vacuum condition, proper inert gas permeates into the outer surface of steel, the hardness of the outer surface of the auxiliary rigid carrier is higher than 40 HRC, the copper sheets are rapidly welded, the adhesion effect is not generated, and the service life of a jig is prolonged. According to the copper sheet welding method using the new auxiliary carrier, the chromium-molybdenum steel system is a steel type of which the high-temperature strength limit and the creep limit are obviously improved, meanwhile, the chromium-molybdenum steel system has good hydrogen corrosion resistance and high-temperature resistance, the binding force of the two copper sheets can reach 0.1-0.5 MPa, the drawing force can reach 8.4-32.5 cm<2> in the high-temperature continuous working process, the copper sheets can be completely combined in a sealed mode, and a better use prospect is brought.

Description

technical field [0001] The invention relates to the field of copper sheet welding, in particular to a copper sheet welding method using a new auxiliary carrier. Background technique [0002] The copper sheet welding method is a supporting method for copper sheet welding. Most of the existing copper sheet welding uses vacuum sintering, which is not only for the appearance requirements of the product, but also can be mass-produced. The manufacturing process requirements of the method are also getting higher and higher. [0003] The existing copper sheet welding method has certain disadvantages in use, the product yield is low by 70%, and a large amount of graphite is used as an auxiliary carrier, which is expensive and graphite dust damages the mechanical processing machine and causes certain damage to the environmental protection. Most copper sheets are welded in a vacuum sintering furnace, and a large amount of graphite is used as an auxiliary carrier. This is because the a...

[0003] The existing copper sheet welding method has certain disadvantages in use, the product yield is low by 70%, and a large amount of graphite is used as an auxiliary carrier, which is expensive and graphite dust damages the mechanical processing machine and causes certain damage to the environmental protection. Most copper sheets are welded in a vacuum sintering furnace, and a large amount of graphite is used as an auxiliary carrier. This is because the auxiliary carrier can be reused under the high temperature of the vacuum sintering furnace, but the cost is too high and the environment is damaged, which is not conducive to people's use. , has brought some adverse effects to people's use process, for this reason, we propose a copper sheet welding method using a new auxiliary carrier
