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.

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.

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.

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?

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

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.

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.

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.

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.
