LASER METAL WELDING

Principle of laser welding

Laser welding is a high energy density process. This characteristics leads to the creation of a vapour cavity surrounded by melted material. 

The thermal energy transferred inside the capillary provides a fine and deep weld. 

Its rapid solidification guarantees the metallurgical bonding.

Benefits

  1. Increased welding productivity up to 800%
  2. Repeatable process
  3. Reduction or suppression of straightening of welded parts
  4. Global reduction of production costs
  5. Mechanical strength at least equivalent to the basic material
  6. Reduction of the welding consumables
  7. Greater freedom for the design of the parts

Advantages of the process

  • Welding time reduced by 10
  • Low distortion of the parts
  • Welding of parts with limited access
  • Automatable process
  • Welding without filling material

List of materials : carbon steels, stainless steels, aluminium and aluminium alloys, nickel bases, titanium bases and titanium alloys, copper and copper alloys, precious metals.

Modelisation and numerical simulation of laser welding 

Modelisation and numerical simulation are used to understand, predict, control or master the thermo-mechanical behaviour of welded joints.
