Laser Welding of Copper
Laser welding of copper is revolutionized by the development of a new blue diode laser. The blue laser beam enables high-quality processing of copper and other non-ferrous metals in industrial processes.
Copper Welding – The Process
With the blue laser, controlled heat conduction welding of copper and other non-ferrous metals with low material thickness is possible for the first time. Material thicknesses of less than one millimeter are no longer a problem. 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. With the help of the blue laser beam, the desired material is melted along the joints. The liquefied materials flow into each other and form the weld seam when they cool down. This process results in particularly smooth seams that are of outstanding quality and therefore highly stable. Basically, the process is the same as with an infrared laser – apart from the wavelength used.
