Introduction
Laser welding is a process that uses a high-powered laser beam to melt and fuse
materials together. The laser beam heats the materials to their melting point, and
then they are joined together. Laser welding is known for its high precision and
ability to create a narrow and deep weld

How Does the Laser Welding Process
Work?
1. Beam Generation
A laser beam is generated using a laser resonator, which amplifies and concentrates the light.
2. Focusing Optics
The laser beam is directed through focusing optics, ensuring the beam is concentrated and has high power
density at the welding point.
3. Welding Process
The focused laser beam strikes the materials to be welded, melting the surfaces and creating a weld pool. As
the beam moves along the joint, the materials fuse together, forming a strong bond.

Types of Laser Welding
• Conduction welding – This method is used for welding
thin materials together. The laser beam heats the
material to its melting point, and then the materials are
joined together by capillary action.
• Deep penetration welding – This method is used for
welding thick materials together. The laser beam heats
the material to its vaporization point, creating a hole in
the material. The walls of the hole then collapse,
creating a strong weld.
• Laser beam welding – This method uses a highpowered laser beam to weld materials together. The
laser beam is directed onto the materials, which are
then melted and fused together.
