Welded steel into bonding and welding two forms. Pressure welding include flash butt welding, resistance spot welding and pressure welding; welding including arc welding and electroslag welding. In addition, steel and embedded parts welded T joint pressure should be used submerged arc welding, electric arc welding can also be perforated or plug welding, but welding current should not be large, reinforced to prevent burns.
Flash butt welding
Flash butt welding are widely used in reinforced and prestressed connection with screw terminals rod welding. Hot-rolled steel welding should be preferred by flash butt welding.
Reinforced flash butt welding (using the welder to make contact with two reinforced by low voltage high current to be reinforced is heated to a certain temperature to soften, axial upsetting pressure, the formation of the welding head.
Reinforced flash butt welding process commonly used continuous flash welding, preheating flash butt welding and flash - preheat - flash welding
, Sometimes to Ⅳ grade steel after welding heat treatment also energized.
