What Is Laser Welding?

Laser (Light Amplification by Stimulated Emission of Radiation) welding is a fusion welding process where metals or thermoplastics are joined using a focused laser beam. It is the most advanced type of welding and finds application across diverse industries spanning from aerospace and medical equipment to fine jewelry making.

How Does Laser Welding Technology Work?

In the laser welding process, a highly concentrated beam of light is focused on the cavity between the materials to be joined. The powerful laser beam melts the materials at their seams and fuses into a joint. With such a highly concentrated heat source being used, laser welding in thin materials can be done at high speeds. In thicker materials, laser welding can produce deep and narrow welds.
