1. Resistance spot welding machine

　　The torch for resistance spot welding has two upper and lower electrodes, and the affordable precision spot welding machine has the functions of conducting current, pressing and dissipating heat. During the welding process, the current conducted through the electrodes uses the resistance heat generated when passing through the welding area to heat the material to a molten or plastic state, and then the weldment is connected under the pressure of the upper and lower electrodes. Resistance spot welding is usually used in the welding of automobile bodies. The assembly of resistance spot welding is simple, automated and mechanized. It has irreplaceable advantages, and there is no need for filler metal during the welding process. The welding area is small, the welding efficiency is high, and the deformation of the weldment is small. Ensure that the structure is beautiful.

　　2. Ultrasonic point machine

　　Ultrasonic spot welding is a solid phase welding technology with low energy input and short welding time. Compared with other easy-to-use precision spot welding machines, it has the advantages of environmental protection and low energy consumption. The principle of ultrasonic spot welding is that under the action of static pressure, the high-frequency vibration energy of the ultrasonic is converted into heat energy through the friction and deformation of the weldment, and the welding material is heated to a plastic state, so that the atoms at the interface are mutually diffused. So as to achieve solid phase connection.

　　Three, laser spot welding machine

　　Laser welding uses a high-energy laser beam as a heat source to irradiate the surface of the workpiece. The precision spot welder makes the material reach a plastic or molten state to achieve metallurgical connection. It is an emerging special processing technology. The advantages of using laser as the welding heat source are its fast welding speed, high precision, relatively small welding heat input, narrow heat-affected zone, and small weldment deformation. It is one of the main ways to connect dissimilar materials. The laser spot welding process parameters are highly flexible and adjustable, which can accurately control the heating area and heating time.
