Study the Application of Laser Welding in the Automotive Transmission Parts
Laser beam of high energy density, melting of the workpiece material welded together, can make the heating affected area and change shape minimum, without the use of flux or for dissimilar materials, particularly strong bonding strength. Laser welding is a high energy of the laser beam as heat source a high precision welding. However, the safe application of new technology is the challenge we face. Laser can damage the eyes, skin, respiratory, central nervous and the whole body. It is generally skin safety standards. View of the laser welding process currently used, the possibility of respiratory hazards in the growth of workers with chronic exposure to hazards by the possibility of laser is growing, so the above five aspects of laser hazards should pay attention.
