With the development of technology and economy, in our daily life everywhere car shadow, you know about the car door, follow the below small make up to find out door has a stamping and welding, welding the door in the middle of a very obvious trace of welding, the door of the car window frame is welded, and the lower part of the door is not a whole;
The one-piece door is up and down two parts as a whole, no welding mark on the door.
One door and welding which good?
One-piece door advantage is whole stamping molding, and the overall intensity than easier to control, welding forming quality is better;
Next to the requirement of steel is higher, the ductility of steel plate must be good enough, but also to a strong enough rigidity, steel consumption will need enough, otherwise there will be a security risk.
Welded door, welding position is not necessarily cause the loss of metal strength, instead, local strength rise, but some toughness will decline.
Aspects such as the dosage of the steel costs will be lower, but in the process of welding quality control is difficult, then does use the welding technology is the security?
Actually many automotive metal parts are using welding technique, and even China's shenzhou rocket has the application of welding technology.
So I decided to things sound or not is not the key welding mouth, but the material.
As a car, make sure that have higher safety coefficient is not confined to the door is a integrated or welded, but rigid, strong in the B column, roof, door anti-collision bones and muscles of materials is used the high strength steel and other factors.
Because of the unique advantages of laser welding technology in automobile manufacture, frame, body, cars, engines, automobile gear, such as the roof cannot leave the welding technology, laser welding has a small deformation, high weld quality, no solder, become the standard of auto parts manufacturing process.
