Abstract

The invention discloses solder and a welding method. The solder comprises, by weight, 5-10% of sulfate, 10-20% of metallic oxide, 5-10% of wetting agents, 30-60% of metal alloy, 5-20% of slag former and the balance diluent. According to a steel claw designed for solving the technical problem of aluminum-steel direct welding by the application of the chemical welding principle, aluminum-steel full-area welding is achieved, specific resistance is reduced, the mechanical strength of the welding surface is improved, the solder is convenient to use, high in welding efficiency and good in welding quality, automation of welding can be achieved, labor intensity of workers is low, and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of electrolytic aluminum, in particular to a welding agent and a welding method used for welding different materials in electrolytic aluminum. Background technique [0002] In recent years, with the rapid development of my country's aluminum industry, especially the electrolytic aluminum industry has become a part of the country's strategic industry, my country's electrolytic aluminum output ranks first in the world, and aluminum production technology has reached or approached the world's advanced level in many aspects. In terms of efficiency and aluminum production, aluminum electrolytic cells will definitely develop in the direction of large-scale and high-current. The technical problems to be solved are: welding under strong magnetic fields and full-interface welding between different materials. These two technical problems directly affect our country. The healthy and stable development of the aluminum elec...
