What are the advantages of spot welding machine classification and double point?

spot welding machine is a kind of mechanical equipment. It 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 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.

Next, let Shenzhen Sester Technology Co., Ltd. introduce several types of spot welding machines!

spot welding machines are divided into general-purpose and special-purpose; according to the number of welding spots welded at the same time, there are single-point, double-point and multi-point; according to the conduction mode, there are unilateral and bilateral; according to the transmission mode of the pressurizing mechanism, There are pedal type, motor cam type, pneumatic type, hydraulic type and composite type (gas-liquid combination type); according to the characteristics of operation, there are non-automatic and automatic; according to the installation, there are fixed type.

When one electrode flows through the other electrode, instantaneous thermal welding is formed at the two contact resistance points, and the welding current flows from the other electrode to this electrode instantaneously along the two workpieces, forming a circuit without damaging the internal structure of the workpiece to be welded. Movable or portable (hanging type); According to the movement direction of the movable electrode (usually the upper electrode) of the welding machine, there are vertical stroke (electrode linear motion) and arc stroke; According to the power supply mode, there are power frequency welding machine (using 50Hz AC power supply), pulse welding machine (DC pulse welding machine, energy storage welding machine, etc.) and frequency conversion welding machine (such as low frequency welding machine).
