Some workpieces need to be annealed after flash butt welding. What is annealing?

The main workpieces that need to be annealed after flash butt welding are ferroalloys, high carbon steels, manganese steels, stainless steels, etc. This is related to the structure of the materials after high temperature welding. The main function of annealing is to reduce the hardness, facilitate cutting and processing, eliminate the internal stress of the metal, stabilize accuracy, and resist deformation and cracks. Make the grains fine and group

Why does it not need to be customized when choosing a butt welding machine for copper wires less than 150 square meters?

Copper wire specifications below 150 square meters correspond to φ0.5~14mm copper wire and copper rods. To meet these specifications, some manufacturers have been producing for nearly 30 years and accumulated a large amount of data. From manual to pneumatic to programmed welding machines, generations of improvements have long been sufficient.

Why should traditional copper wire butt welding machines be upgraded to thyristor control?

Traditional copper wire butt welding machines generally use contactors to control the size of the current. The upper contacts of the contactor connect and break the copper strips below, and they often need to be pressed to connect. We often hear the sound of "bah-bah-bah-bah", the leaves are noisy, and the service life is limited, usually about 5,000 times.
