Application in welding industry

Resistance welding refers to the method of using the resistance heat generated by the current through the weldment and the contact as the heat source to locally heat the weldment and pressurize it for welding at the same time. When welding, there is no need for filler metal, with high productivity and small deformation of weldments, it is easy to realize automation.


Resistance welding is a method that uses the resistance thermal effect produced by the current flowing through the contact surface and adjacent area of the workpiece to heat it to a molten or plastic state to form a metal bond. There are four main methods of resistance welding, namely spot welding, seam welding, projection welding and butt welding.

Raw material
Starting from raw materials, it is very prominent in the stability and consistency of products. Identify different brands of raw materials and mark the batch number. And each batch of raw materials shall be sampled, inspected and archived. Ensure the traceability of each finished product.
From powder to finished products, GeMei strictly controls every process in the production process
Blend
Ensure that the materials in the milling and mixing process can be fully stirred and evenly distributed to ensure the consistency of the internal organization of the product.

Extrusion
The pressing process is the process of powder blank forming. The pressing of powder is completed by isostatic pressing equipment to make its internal structure uniform and dense.

After the metal powder is pressed by isostatic pressing, it is heated at a temperature lower than the melting point of the main components to make the particles connect, so as to improve the performance of the product, which is called sintering.

Sinter

Forging
Forging technology can make materials obtain higher density, better mechanical properties, and play a role in strengthening the surface.
From powder to finished products, GeMei strictly controls every process in the production process
Rolling
The rolling process makes the metal material produce continuous plastic deformation under the pressure of the rotating roll, and obtain the required section shape and properties.

Heat treatment

It can completely eliminate the internal structural stress of the material, give full play to the best performance of the material, and make the material easier for subsequent machining.

Machining
Through turning, milling, cutting, grinding and other mechanical processing procedures, it can be processed into various customized sizes of customers, and ensure that the internal organization of tungsten and molybdenum materials is tight, stress free and free of holes

From powder to finished products, GeMei strictly controls every process in the production process
Quality testing
Starting from raw materials, quality inspection and control, as well as quality inspection and sampling inspection of each process, continue to ensure the process quality control of each process of the product.
