Newly purchasedFlash butt welding machineBefore use, you will generally feel a little at a loss. Xinxing Welding recommends that you please pay attention to some matters before, during and after welding according to the instructions.
Workpiece preparation for flash butt welding includes: end face geometry, blank end processing and surface cleaning. 1. During flash butt welding, the geometry and size of the butt surfaces of the two workpieces should be basically the same at least in the electrode section. Otherwise, it will not be possible to ensure that the heating and plastic deformation of the two workpieces are consistent, which will affect the quality of the joint. In production, the difference in diameter of circular workpieces should not exceed 15%.Shape workpieces and tubular workpieces should not exceed 10%. 2. When flash butt welding large-section workpieces, it is best to chamfer the end of a workpiece to increase the current density to facilitate flashing. This eliminates the need for preheating or increasing the secondary voltage during the initial flash phase. 3. The butt welding blank end must be processed on a cutting machine, sawing machine, and hydraulic shear in advance, and then the end face must be cleaned. During flash butt welding, the end metal is burned during flashing, so the requirements for end face cleaning are not very strict. However, the cleaning requirements for the contact surface between the clamp and the workpiece should be the same as for resistance butt welding.
