STTE Technology to introduce you to the automatic spot welding machine operating requirements

automatic spot welding machine adopts the principle of double-sided double-point over-current welding. when working, two electrodes pressurize the workpiece to form a certain contact resistance between the two layers of metal under the pressure of the two electrodes. when the welding current flows from one electrode to the other electrode, an instantaneous thermal fusion is formed at the two contact resistance points, and the welding current instantly 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 type ultrasonic automatic welding. Compared with the 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, thus improving the quality of the product; Eliminate the cost caused by the use of flux, low rejection rate, and can be repeated processing;

2. The control device mainly provides signals to control the action of the resistance welding machine to switch on and off the welding current, control the welding current value, and carry out fault monitoring and treatment

3. The small automatic spot welding machine system consists 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, and the opening degree of the welding tongs can be changed by switching the stroke control handle, which can be divided into large opening and small opening to meet the requirements of welding operation. The normal state is short-stroke opening of the welding tongs. When the control button is switched to the "power on" position, the handle switch is pulled to clamp and pressurize the welding tongs. At the same time, the current returns to the short-stroke opening state after completing a welding cycle under the control of the control system.
