AI Technical Summary

Technical Problem

In the prior art, high-speed blowing of the protective airflow during argon arc welding causes air to invade the melt pool, resulting in welding defects and insufficient crystallization.

Method used

By using a pressure reducing valve and air pipe in the aluminum veneer welding device, the protective gas slowly fills the welding pool from bottom to top to avoid the formation of high-speed air flow.

Benefits of technology

Reduce the occurrence of welding defects and improve the welding quality and strength.

Abstract

The invention relates to an aluminum veneer welding device, which belongs to the technical field of welding, and comprises a main machine, a resistance welding gun, a welding pool, an air pipe and a pressure reducing valve, the welding pool is connected with an electrode of the main machine, and the welding pool is used for placing an aluminum substrate; the gas pipe communicates with the bottom of the welding pool; the pressure reducing valve is connected to the end, away from the welding pool, of the gas pipe and connected with a protective gas source through an electromagnetic valve. Protective gas enters the welding pool through the pressure reducing valve and the gas pipe so as to discharge oxygen in the welding pool; the density of the protective gas is greater than that of the oxygen; the technical problem of welding defects caused by high-speed blowing of protective gas in the prior art can be solved.
