Automatic welding equipment system consists of automatic welding equipment including welding energy equipment, welding head and welding control system.
1, welding energy equipment used to provide the energy required for welding. Commonly used is a variety of arc welding power supply, also known as welding machine. Its no-load voltage of 60 ~ 100 volts, the working voltage of 25 ~ 45 volts, the output current of 50 ~ 1000 amps. Manual arc welding, the arc length often changes, causing changes in welding voltage. In order to stabilize the welding current, the external characteristics of the arc welding power supply used should be steeply falling, that is, with the change in output voltage, the change in output current should be very small.
Molten electrode gas shielded arc welding and submerged arc welding can be used flat characteristic power supply, its output voltage changes in the current change is very small. Arc welding power supply generally have arc welding transformer, DC arc welding generator and arc welding rectifier. Arc welding transformers provide alternating current and are more widely used. DC arc welding generator to provide direct current, more complex manufacturing, consume more materials and lower efficiency, gradually replaced by the trend of arc welding rectifier.
