Practical guidance for comparing processes and equipment formats.
First of all, Xinxing steel bar flash butt welding is a 0-degree horizontal butt joint, and electroslag pressure welding is a 90-degree vertical butt joint. Their principles and processes are also different.

In flash butt welding or resistance butt welding, due to the influence of the resistance heat source that changes the workpiece port section from solid to liquid to fused solid, the structure and properties of metals and alloys after welding will undergo some changes. Therefore, if we understand the chemical composition and properties of metal and alloy welded joints, we can understand how they can be used during welding.

Most domestic manufacturers like to make simple copper wire butt welding machines. Of course, there are also complex iron wire and steel wire butt welding machines that are copied from Germany and Japan. The difference between them is: 1. The simple butt welding machine only retains the welding and tempering functions, while the complex type has only the welding and tempering function on the fuselage.

There are indeed many styles of multi-functional butt welding machines. Their heads are different, the positioning principles used are different, and the materials used are also different. These are designed and manufactured according to the cross-sectional area or diameter of wires, rods, and pipes made of mild steel, stainless steel, copper, aluminum, titanium and other materials.
Read articleThe power of copper wire butt welding machines ranges from small to large. The diameter or cross-sectional area of the copper wire is mainly used to determine the corresponding power of the butt welding machine. There are also manual and pneumatic, and more complicated ones are ordinary and programmed. Depending on the transformer, the difference is also relatively large.

When you choose a high-power resistance butt welding machine, the focus should be on 1. Power supply (transformer) 2. Control system 3. Pneumatic system. Among them, the power transformer is the heart of the welding machine. If the heart is not good and the life is not long, it means that everything is in vain.
Read articleThe multifunctional butt welding machine is a resistance butt welding machine. Compared with other argon arc welding machines and laser welding machines, it has a wider welding range and more advantages.

The tellurium copper rod butt welding machine is the same as other water-cooled pneumatic butt welding machines. It has a complex structure, but its installation is relatively simple. Just follow the following points.

1. Docking: Since tellurium does not have a strong ability to inhibit recrystallization and the material softens significantly during annealing, it is still difficult to meet tailor-made parameters when making tellurium copper into strips or rods. Xinxing generally uses a CNC version of a resistance butt welding machine for butt welding.
