Laser welding

Listing ID #3857453

Laser welding of materials can be realized by either Heat conduction or key hole/ deep penetration.

Heat Conduction Welding: laser beam with increased spot size and reduced energy density on material makes ratio between welding seam width to welding penetration >1. This means welding with shallow depth of penetration compared to bigger seam width. This kind of welding is ideal for wide joint with high welding seam quality which requires minimum post welding processing.

Deep penetration welding: laser beam with smaller spot size and increased energy density interact with material gives smaller and deep welding seam. This is due to plasma pressure generated due to key hole generated in melting pool as a result of high laser intensity. The key hole welding leave its signature on seam geometry and requires post processing.

• Low thermal load and low distortion
• Smooth, regular and pore-free welding
• High process stability at high welding speeds
• Keyhole welding and heat conduction welding
• Reduced costs for investment and operation
• Highest reliability for serial production
