Introduction of several types of spot welding machine

1. resistance spot welding machine

The welding gun for resistance spot welding has two upper and lower electrodes. The affordable precision spot welding machine has the functions of conducting current, pressurizing and heat dissipation. During the welding process, the current conducted through the electrodes heats the material to a molten or plastic state by using the resistance heat generated when passing through the welding area, 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 simple assembly, automation and mechanization of resistance spot welding have irreplaceable advantages, and no filler metal is required during the welding process, the welding area is small, the welding efficiency is high, and the weldment deformation is small. Ensure the structure is beautiful.

2. Ultrasonic Spot Machine

Welding 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 green, 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 ultrasonic wave is converted into heat energy through the friction and deformation generated by the welded parts, and the welding material is heated to a plastic state, so that the atoms at the interface diffuse each other. In order to achieve solid-phase connection.

3. laser spot welding machine

laser welding is to use high-energy laser beam as a heat source to irradiate the surface of the workpiece. The precision spot welding machine makes the material reach a plastic or molten state to realize metallurgical connection. It is a new special processing technology. The advantage of using laser as the welding heat source is that it has the advantages of fast welding speed, high precision, relatively small welding heat input, narrow heat affected zone and small welding deformation, which is one of the main ways to connect dissimilar materials. The laser spot welding process parameters are highly flexible and adjustable, and the heating area and heating time can be accurately controlled.
