Overview of the Laser Welding Process
Laser welding utilizes focused beams of light to join materials together. The process involves the following steps:
- Preparation: The materials to be welded are cleaned and aligned.
- Focusing the Laser: A laser beam is focused on the joint area, generating intense heat.
- Melting and Fusing: The heat melts the edges of the materials, which then fuse together as they cool.
- Cooling: The welded joint solidifies, creating a strong bond.
This method boasts numerous advantages, including minimal thermal distortion, high welding speeds, and the ability to weld complex shapes.
