Application of Laser Welding Technology in Automobile Doors
Date:2022-07-14 Publisher:

With the development of technology and economy, the shadow of cars can be seen everywhere in our daily life. Do you know anything about car doors?

The door has a one-piece stamped and welded door. There is a very obvious trace of welding in the middle of the welded door. The window frame of the door is welded, and it is not a whole with the lower part of the door; and the one-piece door is The upper and lower parts are a whole, and there are no welding marks on the door.

Which one is better, the one-piece door or the welded door? The advantage of the one-piece door is that it is integrally stamped. The overall strength is easier to control than the welded door, and the quality is better. Secondly, the requirements for steel are higher, and the ductility of the steel plate must be sufficient. Good, and the rigidity should be strong enough, and the amount of steel should be sufficient, otherwise there will be potential safety hazards. For welded doors, the welding position does not necessarily cause the metal strength to decrease, but the local strength increases, but the toughness decreases. The cost of steel consumption and other aspects will be lower, but the quality control during the welding process is more difficult, so is there a safety problem when using welding technology? In fact, many metal parts of automobiles use welding technology, and even my country's Shenzhou rocket has the application of welding technology. So the key to determining whether something is strong or not is not the weld, but the material. As a car, ensuring a high safety factor is not limited to whether the doors are integrally formed or welded, but whether the materials used for rigid and strong B-pillars, roofs, and interior door anti-collision ribs are used. Factors such as high-strength steel.

Due to the unique advantages of laser welding technology, in automobile manufacturing, the frame, body, carriage, engine, automobile gear, roof, etc. are all inseparable from welding technology. Laser welding has the advantages of small deformation, high weld quality, and no need for solder. It has become the standard process of auto parts manufacturing.
