The automobile automatic welding production line is mai […]
Welding is a necessary process method in modern machinery manufacturing and is widely used in automobile manufacturing. With the advancement of technology, new welding processes, new materials and new methods are continuously used in automobile manufacturing. Welding problems of coated steel plates and light metal materials. Polymer materials, composite materials, dissimilar materials, and special materials have proposed new methods for automobile welding. challenge. Robots and automation technology in the process of automobile welding have greatly changed the face of automobile welding.
In terms of body welding technology, including the common welding principle, the metal is actually liquefied and then cooled to dissolve together. The body of the car is welded by four steel plates: ordinary steel, spot welding, and the steel plates are connected by welding points one by one. Laser welding uses the high temperature of the laser to disrupt the molecular structure in the two steel plates, and the molecules are rearranged so that the molecules in the two steel plates are dissolved into one body. So from a physical point of view, laser welding is to turn two steel plates into one steel plate, so it has higher strength than ordinary welding.
