Laser welding is a precise joining technique that uses a focused beam of light to melt and fuse materials together. This method is commonly used in industries such as automotive and aerospace due to its ability to create strong, clean welds with minimal distortion. The process involves directing a high-energy laser beam onto the surfaces of the materials being joined. The intense heat generated by the laser melts the edges of the materials, allowing them to bond as they cool. Laser welding can be applied to various materials, including metals and plastics, making it a versatile option for manufacturing.
