The butt welding machine mainly uses the contact resistance of the workpiece to generate heat to heat the workpiece, the metal surface melts, the temperature gradient is large, and the heat affected zone is relatively small.
Welds are formed under the condition that the solid phase metal of the workpiece is plastically deformed to form a common grain; the structure and composition of the weld are close to the base metal (or heat treated), and it is easier to weld the workpiece with higher strength.
The welding process has a self-protection function that exhausts air and reduces metal oxidation; upset forging can also discharge oxides out of the weld with the liquid metal. There are fewer defects such as weld inclusions and incomplete penetration.
过程具有较强的自调节功能，对严格保持规范一致性要求较低，焊接质量稳定。 The welding process has a strong self-adjusting function, has lower requirements for strictly maintaining the consistency of specifications, and has stable welding quality. The unit welding cross-sectional area requires small electrical power. Welding of low-carbon steel requires only (0.1-0.3) KVA / mm2 power. Welding productivity is high, and welding a joint takes only a few seconds to tens of seconds.
