The main part of the Butt fusion welding machines is a step-down transformer. At both ends of the secondary coil are the workpiece and the electrode to be welded. During operation, the arc is ignited,...

Safety operation rules of butt welding machine 1. The staff should be familiar with the welding process of the butt welding machine: (1) Continuous flash welding: continuous flashing, upsetting, and e...

The Butt fusion welding machines is divided according to the welding method: flash butt welding machine, steel butt welding machine, copper rod butt welding machine Welds are formed under the conditio...

Butt welding machine actually uses the resistance to generate heat when the workpiece is in contact with the mouth, thereby heating the workpiece and melting the metal surface, and the weld is formed ...

1. Reduce the cross-sectional area of the weld and, on the premise of obtaining a complete weld with no defects beyond the standard, use a smaller bevel size (angle and clearance) as much as possible....

1. The joint should be set as far as possible in the place where the force is small, and the key part of the structure where the force is large should be avoided. In the seismic design, avoid the beam...

1. According to the design requirements, the welding method of the engineering reinforcement connection is selected. The welding methods are mainly arc welding and flash butt welding, and arc welding ...

1. Before operation, check whether all tools, electric welders, power switches and circuits are good, whether the metal casing is safely and reliably grounded, whether the inlet and outlet wires have ...
