Laser Welding Machine

The machine is widely used for laser welding processes. Laser welding is a type of fusion welding, which is mainly used to weld a wide range of materials. The machine can also be used to create selective area spot welds or linear continuous seam welds.

Welding Process
The welding process involves focusing the laser beam towards an area, which causes the materials to be welded to change from solid to liquid state, and as soon as the laser beam is removed, back to solid state.

Types of Laser Welding
Basically, there are two types of laser welding processes:

• Laser conduction welding: The process depends on the conductivity of the material to be welded. In this process, the laser beam is applied to particular area of the material, which in contact conducts heat into the area to be joined. The application of laser beam to a specific area results in generation of heat. The resulting heat causes the material to change from solid to liquid state and also joins the two separate liquid materials. The change of the material back to solid state results in joining or welding at that location.
• Laser penetration welding: The process involves focusing the laser beam at a single location or area till the combination of materials are heated to a liquid state and a part of the material evaporates, thereby creating a hole inside the material. The hoe created is equivalent to the thickness of the material. When the materials cool down from a liquid state to a solid state, it implies the welding of the materials at that location.
