Automated Continuous Fiber Laser Welding Machine SM-AW1000 to SM-AW6000
DC arc welding generators provide direct current, which is more complex to manufacture, consumes more materials and has lower efficiency, and is gradually being replaced by arc welding rectifiers. Arc welding rectifier is a DC arc welding power source developed in the 1950s, which uses silicon diodes or thyristors as rectifiers. The transistor type arc welding power source composed of high-power transistors that emerged in the 1960s can achieve high control accuracy and excellent performance, but the cost is relatively high. The simpler welding energy equipment for resistance welding is the resistance welding transformer, with a no-load voltage range of 1-36 volts and a current ranging from several thousand to tens of thousands of amperes. The welding machine equipped with this welding energy equipment is called an AC resistance welding machine. There are also low-frequency resistance welding machines, DC pulse resistance welding machines, capacitive energy storage resistance welding machines, and secondary rectification resistance welding machines.
