The main workpieces that need to be tempered after flash butt welding are steel and copper. The function of tempering is to reduce the brittleness of the metal, eliminate or reduce internal stress, obtain the required mechanical properties, stabilize the size of the workpiece, and facilitate cutting. Xinxing editor also often sees direct tempering after butt welding.

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

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.

Flash butt welding machine, also known as flash butt welding machine, is a type of resistance welding machine. The principle is that two metal workpiece ports are in contact, conduct electricity through the contact points of the ports, and then use the resistance heat of the workpiece itself to heat the workpiece and flash continuously to weld.
