Plastic ExtRusion Welder for Sale, here is a CNC foot welding machine. Not only can iron, steel workpieces, but also welded galvanized plates and copper workpieces. Different electrodes of different materials should be used. The manufacturers are generally standard for standard. Everyone should choose according to the characteristics of their own workpieces.

■ First of all, no matter which metal welded, we need to understand the characteristics and functions that the electrode must have. Its characteristics are as follows:

1. High conductivity and high thermal conductivity;

2. The strength and hardness are also high at high temperature, and they have good resistance to deformation and abrasion;

3. It is difficult to form alloys with the workpiece at high temperature. The physical performance is stable and it is not easy to adhere;

4. The electrode manufacturing cost is low, easy to process, and it is easy to replace after deformation or damage;

5. The electrode oxidation rate is low.

■ Electrical function

1. Pass the heat of welding current, pressure and workpiece surface;

2. The quality of the electrode directly affects the welding process, production efficiency and welding quality.

■ There are 3 types of common electrode materials

1. Copper T2, hardness HRB: 40-52 conductivity: 90%IACS or 57ms/m softening temperature: 370 ° C

2. Chromium Copper, hardness HRB: 78 ~ 88 conductivity: 90%IACS or 43ms/m softening temperature: 550 ° C

3. Alumina and copper, that is, to diffuse copper hardness HRB: 84 conductivity: 90%IACS, softened temperature: 900C

The life of alumina and copper is more than 3 times that of chromium chromium copper (CUCRZR), and anti -adhesion is attached.
