Energy equipment, including welding, the welding head and welding control system.
â‘  welding energy equipment: for the welding energy required. Commonly used in a variety of welding power source, also known as the welding machine. No-load voltage of 60 ~ 100 V, operating voltage 25 to 45 volts, the output current of 50 ~ 1000 Ann. Manual arc welding, arc length, often change process
, Voltage changes caused by welding. To make stable welding current, outside of the arc welding power supply features should be plunged, as the output voltage changes, the change of the output current should be very small. MIG arc welding and submerged arc welding can be flat characteristic power, its output voltage changes when the current changes. The arc welding power sources are generally arc welding transformer, the DC arc welding generator and arc welding rectifier. Arc welding transformer is alternating current, and a wider application. DC DC arc welding generators, manufacturing is more complex, and consumable materials are more and less efficient, there is a trend that gradually replaced by arc welding rectifier. Arc welding rectifier DC arc welding power source is developed in the 1950s, silicon diode or thyristor rectifier. 1960s power transistor transistor-type arc welding power source, high control accuracy and excellent performance, but the cost is high. ERW welding energy equipment is relatively simple resistance welding transformer no-load voltage range of 1 to 36 volts, the current from a few thousand to tens of thousands of security. With this welder welding energy device known as the AC resistance welding machine. Other low-frequency resistance welding machine, resistance welding machines, capacitor discharge resistance welding machine and the secondary rectification of the DC pulse resistance welding machine â‘¡ welding head: it is the role of the welding energy equipment output energy is converted to a welding heat, and continue sent to the Welding Material, while the head itself to move forward to achieve welding. Manual arc Welding Electrode  holder, with the melting of the welding rod must constantly manually sent to the welding down, and move forward to form the weld. Automatic welding machine automatically sent to the wire agencies, organic head and running gear and head to move forward. Commonly used in the car and hanging two kinds of head. The welding head resistance spot and projection welding electrode and its pressure institutions to exert pressure and power on the workpiece. Seam welding another drive mechanism to drive the workpiece move. Static and dynamic jig and fixture clamping mechanism, as well as mobile fixture welding equipment in the butt when
And upsetting agencies. (3) welding control system: its role is to control the entire welding process, including control of welding procedures and welding parameters. General AC arc welding machine control system. Efficiency or precision welder with electronic circuits, digital circuits and microprocessor control.
