How Does Laser Welding Work?

Laser welding is a process of joining two materials together using a focused beam of high-powered laser light. The laser beam generates intense heat, which melts the material and fuses the pieces together. The process is highly precise and is commonly used in the manufacturing industry for bonding metals and plastics.

In laser welding, the laser beam is directed onto the surface of the material to be welded. The beam then melts the material, creating a molten pool that cools and solidifies to form a joint. The key advantage of laser welding is its ability to create a strong, permanent bond without the need for additional materials such as rivets or adhesives.

Due to the precision and speed of the laser, it is possible to achieve very small welds in very precise locations on a component. This makes laser welding ideal for applications where accuracy and consistency are essential, such as in the aerospace and medical device industries.
