The automatic spot welding machine adopts the principle of double-sided double-point overcurrent welding. When working, the two electrodes pressurize the workpiece so that the two layers of metal form a certain contact resistance under the pressure of the two electrodes, and the welding current flows from one electrode to the other When electrodes are used, an instantaneous thermal fusion is formed at the two contact resistance points, and the welding current flows from the other electrode along the two workpieces to this electrode to form a loop, and will not damage the internal structure of the welded workpiece.

　　1. Turntable ultrasonic automatic welding. Compared with traditional vibration friction welding and heating melting welding, ultrasonic welding has the following characteristics: fast, welding is usually completed in one second-clean, because no flux is used, the risk of pollution is greatly reduced, thereby improving the quality of the product ; Eliminate the cost due to the use of flux, low scrap rate, and repeat processing;

　　2. The control device mainly provides signals to control the action of the resistance welding machine to turn on and off the welding current, control the value of the welding current, and perform fault monitoring and handling

　　3. The small automatic spot welding machine system is composed of three parts: mechanical device, power supply device and control device. In order to meet the requirements of the welding process, the pressurizing mechanism (welding tongs) adopts a double-stroke fast pneumatic transmission mechanism. The opening degree of the welding tongs can be changed by switching the stroke control handle. It can be divided into large opening and small opening to meet the requirements of welding operation. The normal state is that the welding tongs are opened for a short stroke. When the control button is switched to the "power on" position, the tongs will be clamped and pressurized when the handle switch is pressed. At the same time, the current returns to the short stroke after completing a welding cycle under the control of the control system. Open state.
