Because of the special working condition of anode steel claw, it is required to have good electrical conductivity and sufficient strength. Due to oxidation, corrosion and other factors, the anode steel claw used repeatedly will become thin, hook, fracture, etc. in electrolysis production. When it is lower than the normal use of the use of standards, it should be repair or scrap replacement.
The traditional manual welding method mainly has the following problems:
The effective welding area is small, the mechanical properties of the joint are poor, and the pressure drop of the welding joint is high.
After repair, the service life of the claw leg is short, and the repair rate is high, so the cost of repeated maintenance of it is high.
The labor intensity and cost is high, but the welding efficiency is low and the repair quality is unstable.
Combined with the actual situation of anode steel claw repair of electrolytic aluminum enterprises at home and abroad, our company has developed the JW-57A full cross section welding equipment of anode claw after in-depth research, and realized the vertical joint full section automatic welding at the welding joint. The equipment has been promoted and applied in many domestic electrolytic aluminum enterprises, and this technology solves many problems existing in the traditional manual welding method. Manual labor intensity can be significantly reduced, welding efficiency and welding quality have been greatly improved, which is conducive to electrolytic aluminum enterprises to reduce ton aluminum power consumption and production and operating costs.
