Laser welding decrease the weight of the product

Laser welding is used in many field today Automotive, Aircraft, home applicance the main raison is :

Laser welding decrease the weight of the product.

Automotive industry

Big manufacturers in the Automobile industry are pursuing development of vehicles with excellent fuel economy considering environmental sustainability

Lightweight technologies are important in that respect, so laser welding technology is applied to continuous joining, which can contribute to lightweight bodies

But it can be difficult to hold weld quality because welding defects often occur at the lap joint of thin steel sheets with large gaps.

In the automotive field, they need high productivity and high welding speed.

The laser-arc hybrid welding technology could weld joints with gaps of about 100% the upper sheet thickness, however, burn-through defects might occur, owing to high arc current in case of larger gap.

Aircraft industry

Laser welding make the aircraft lighter, that one of the reason why Laser welding will be used in this fied.The main focus of laser welding aircraft structures is on the development and testing of new plant concepts.

We have to weld in 2 sided-simultaneous and on welding in areas with restricted access.

A technology with great potential, the laser welding of aircraft parts is regarded as a pioneering technology for the efficient manufacturing of weight-reduced, metal fuselage structures.

CMF is confident to developp this technology in continuous welding machine for tubes and shells, using in many field, automotive, home appliance, chemney flues.
