Welding performance of copper stamping parts Fuse End Cap and Contact

1. Strong thermal conductivity, Fuse Copper Contact Knife Cap has high thermal conductivity, and requires a high-power heat source; preheating the weldment can be used for welding End Cap and Contact.

2. The fluidity is large, and the molten copper liquid has good fluidity, and can only be welded in the flat welding position. If one-side butt welding is to be performed in a spatial position, a backing plate must be added to ensure penetration and obtain good forming.

3. The thermal expansion and cold contraction are large, and the coefficient of linear expansion of Copper End Cap and Contact Welding Components is large, and the phenomenon of thermal expansion and cold contraction during the welding process is particularly obvious, so the deformation after welding is large.

4. Oxidation, copper of Design Welded Joints is easily oxidized in liquid state to form cuprous oxide, which is dissolved in copper liquid. During crystallization, a eutectic with a lower melting point is formed, which exists on the grain boundary of copper End Cap and Terminal, which reduces the plasticity and easily causes cracks.

5. Stomata, the solubility of hydrogen in liquid copper is very large; after solidification, the solubility decreases again. During welding Outer Cap and Contact, the welding seam cools very quickly, and the excess hydrogen does not have time to escape, so hydrogen holes are formed. In addition, the cuprous oxide at high temperature reacts with hydrogen and carbon monoxide to generate water vapor and carbon dioxide. If they cannot escape completely before solidification, pores will also be formed.
