Automatic 400W YAG Laser Medical Tool Mould Repair Laser Welder Stainless Steel Mould Repair Laser Welding Machine For Aluminum.

Laser welding is a welding technique used to join multiple pieces of metal through the use of a laser beam. The laser weldingsystem provides a concentrated heat source, allowing for narrow, deep welds and high welding rates. This process is used frequently in high volume welding applications, such as in the Automotive Industry.
