Before using a newly purchased flash butt welding machine, you will generally feel a little at a loss. Xinxing Welding recommends that you please pay attention to some matters before welding, during welding and after welding according to the instructions.

Theoretically, almost all steel and non-ferrous metals can be flash butt welded, but to obtain high-quality joints, Xinxing Welding recommends taking necessary process measures based on the relevant characteristics of the metal.

Whether it can be welded with the Xinxing flash butt welder depends on the type of steel? Steel is divided into: (1) Ferritic F steel (2) Austenitic (A) steel (3) Cementite Fe C steel (4) Pearlite (P) steel (5) Martensite (M) steel

This time Xinxing used a resistance pneumatic automatic butt welding machine to test weld the 6 series and 7 series aluminum alloy round rods with a diameter of 21mm that the customer sent yesterday. What do you think the effect was?

Welding steel mainly depends on the carbon content to determine whether it can be welded or not. In order to ensure high-quality welded joints, Xinxing editor recommends giving priority to low carbon steel, and then medium carbon steel.

Although the Xinxing automatic flash butt welding machine has a high degree of automation and does not require high personnel, some operating points must still be followed to avoid safety accidents.

Xinxing automatic flash butt welding machine always sets the parameters according to the product before leaving the factory and performs trial welding. Some common problems generally occur when the welding specifications are changed or the product is not debugged. There are 9 special points in reserve.

Xinxing automatic flash butt welding machine does not have strict requirements on the end face of the workpiece. It can eliminate the grinding process of the end face of the workpiece, simplify the operation steps and improve the production efficiency. Because the contact area is small during flash, the current density at the contact point is large, the heat is concentrated, and the heating is rapid, so the heat affected zone is small, the joint is small and of good quality.

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
