Application of Capacitor Energy Storage Spot Welder in the Automobile Industry

The characteristics of the capacitor energy storage welding machine determine that it is very suitable for hard standard welding, that is, short time and high current. There are a large number of components in the automotive industry that require projection welding of nuts, bolts and multi-point projection welding. The performance of the machine in projection welding is very perfect, so the capacitive energy storage welding machine has a broad application space in the projection welding of parts in the automotive industry.

The projection welding of nuts and bolts in the automobile industry includes four corners, hexagons, rounds, special shapes, etc. According to the boss, there are convex points, ribs, crescent convex, ring convex, etc., these nuts/bolts need to be welded on the plate by hard specification welding , And the energy storage welder has excellent performance in projection welding of these products, which can ensure the strength without damaging the threads. Especially now, more and more high-strength plates and thermoformed plates are used. The physical properties of these materials The performance makes it more difficult for general welding machines to achieve stable projection welding results, while capacitive energy storage welding machines have a very large current output in a very short time, which is very suitable for projection welding of these products.

For better connection strength and efficiency, some parts in the automobile industry adopt multi-point projection welding. During projection welding, the same current and pressure distribution is required at each welding point. The instantaneous DC output and peak value of the capacitor energy storage welding machine are high. The characteristics of this feature can fully distribute the current to each convex solder joint, supplemented by rigid pressurization to make the multi-bump welding fully and balanced, and the connection strength after welding is very high, which also makes the capacitor energy storage welding machine in the automotive industry The application is getting wider and wider.
