Laser Welding

Laser Welding – The Process

The blue laser enables controlled welding of copper and other non-ferrous metals with low material thickness. Whereas thin foils were previously cut rather than joined with an infrared laser, the blue laser can now be used to process the material in a targeted and controlled manner. The blue laser beam is used to melt the desired material along the joints. The liquefied materials flow into each other and form the weld seam as they cool. This process produces particularly smooth seams that are of excellent quality and therefore highly stable. The process is basically the same as with an infrared laser - apart from the wavelength used.

Advantages of Welding with Blue Ultra Brillant Diode Lasers

Non-ferrous metals absorbing the blue light spectrum seven to twenty times better than infrared light (see graphic)
Smooth and stable process due to continous energy input
Improvement of micro welding processes of non-ferrous metals
High efficient welding of thin foils and sheets as well as filigree parts
Wobbling to generate large connection areas
Smooth welding seams, no rework needed
