new starAutomatic flash butt welding machineAlways set the parameters according to the product and test weld it before leaving the factory. Some common problems generally occur when the welding specifications are changed or the product cannot be debugged. There are 9 special points for backup.
1. Burning is too violent and produces a strong explosion sound
Solution: Reduce the number of transformer stages; slow down the burning speed
2. The flash is unstable
solveMethod:Remove oxides from the bottom and surface of the electrode; increase the number of transformer stages; speed up the burning speed
3. There is oxide film, incomplete welding or slag inclusion in the joint
solveMethod:Increase the degree of preheating; speed up the degree of burning when approaching upsetting; ensure the electrified upsetting process; speed up the upsetting speed; increase the upsetting pressure.
4. There are shrinkage holes in the joints
solveMethod:Reduce the number of transformer stages; avoid excessively violent burning process; appropriately increase the upsetting allowance and upsetting pressure.
5. The weld is overheated
solveMethod:Reduce the degree of preheating; speed up the burning speed and shorten the welding time; avoid excessive live upsetting.
6. Joint cracks
solveMethod:Check the carbon, sulfur, and phosphorus content of the steel bars. If the steel bars do not meet the requirements, replace the steel bars; adopt a low-frequency preheating method to increase the degree of preheating.
7. Small surface melting and burns
solveMethod:Eliminate rust and oil stains on the clamped parts of the workpiece; eliminate oxides on the inner surface of the electrode; improve the shape of the electrode notch and increase the contact area;Clamp the workpiece.
8. The joint axis deviates or bends
solveMethod:Correctly adjust the electrode position; trim the electrode jaws or replace deformed electrodes; cut off or straighten the elbows of the steel bars
9. The joints are burned unevenly
solveMethod:Increase the degree of preheating; control secondary flash to avoid premature upsetting.

Metal pipe butt welding
Summary of information:
Metal pipes include iron pipes, stainless steel pipes, copper alloy pipes, aluminum alloy pipes, etc. They are mainly used in furniture, boilers, chemical industry, pipelines, planting sheds, air conditioners, cold storage, aerospace, aviation, electrical appliances, agriculture, and electromechanical. Their butt welding is generally selected based on the different materials. Some use resistance butt welding machines, and some use
Metal pipes include iron pipes, stainless steel pipes, copper alloy pipes, aluminum alloy pipes, etc. They are mainly used in furniture, boilers, chemical industry, pipelines, planting sheds, air conditioners, cold storage, aerospace, aviation, electrical appliances, agriculture, and electromechanical. Their butt welding is generally selected based on the different materials. Some use resistance butt welding machines, and some use flash butt welding machines.
There are two options for the iron pipe type, resistance butt welding and flash butt welding. If the budget is insufficient, resistance butt welding can be used. There are also semi-automatic butt welding and pneumatic butt welding. Semi-automatic butt welding is more affordable. Compared with flash butt welding, resistance butt welding has a larger weld and takes longer to polish, but there is no flash spatter. Flash butt welding.
Due to the shortcomings of fast heat generation and slow heat dissipation, stainless steel pipes are prone to cracks and hardening during ordinary butt welding. Flash butt welding machines are generally used for welding.
Copper alloy pipes, aluminum alloy pipes and copper-aluminum pipes are currently welded by resistance butt welding method, mainly using pneumatic automatic butt welding machines.
Its general points are
1. All are welded using high-current, short-time, hard-standard welding parameters.
2. Use customized positioning molds
3. Except for special electrodes used for welding copper, chromium zirconium copper electrodes are used for other purposes.
