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.

Good welding quality:

Excellent full section welding and joint performance: The effective weld area of the welded joint can reach the same cross section of the base material, and the mechanical properties and electrical conductivity of the joint are equivalent to those of the base material;

Stable and reliable welding quality: Welding parameters can be adjusted as needed to fully guarantee welding quality.

It can adjust the composition of the wire according to the material of the customer's steel claw to improve the welding quality.

High welding efficiency: For steel claws of all sizes in China, the welding time for a single claw head with a diameter of 160mm is about 10min.

Low cost:

Vertical seam welding can reduce labor and material costs.

Automatic welding of equipment can significantly improve labor productivity, and it can also effectively reduce labor costs and labor intensity.

After repair, the service life of the steel claw is obviously extended and the maintenance frequency is reduced.

The equipment can realize the automatic welding of the full section of the vertical seam at the welding joint;

It adopts automatic welding of equipment instead of manual operation;

The production line is suitable for welding of steel claws of different structures and sizes, which can not only repair old steel claws, but also weld new structural steel claws.
