Because of the special working condition of anode stub, it is required to have good electrical conductivity and sufficient strength. Due to oxidation, corrosion and other factors, the anode stub used repeatedly will become thiner, hooked, carcked, etc. in electrolysis production. When it is lower than the normal usage standards, it should be repaired, scrap or replaced.

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 voltage drop of the welding joint is high.

After repair, the service life of the stub is short, and the repair rate is high, so the cost of repeated maintenance 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 stub 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. It can significantly reduce manual labor intensity, greatly improve welding efficiency and welding quality, and help electrolytic aluminum companies reduce power consumption per ton of aluminum and production and operation 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 stub to improve the welding quality.

High welding efficiency: For stub of all sizes in China, the welding time for a single claw 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 stub 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 stub of different structures and sizes, which can not only repair old stubs, but also weld new structural stubs.
