LASER PRECISION WELDING – HIGH-STRENGTH WELDED JOINTS WITHOUT ADDITIONAL MATERIAL

Laser precision welding is a modern joining technology and is used when conventional welding methods cannot meet the requirements. Due to the highly focused laser, very fine welding spots or seams with high strength and tightness are possible.

Because of the high power density in the focus, the very short process times and the energy supply that can be precisely metered by laser parameters, even material combinations that are difficult to weld conventionally can be successfully joined with lasers.

PROCESS – HEAT CONDUCTION OR KEYHOLE

Laser precision welding uses a focused laser beam as the energy source. The joining partners are permanently joined by a relative movement between the laser beam and the workpiece. The processing procedure involves an inert gas, such as argon or nitrogen, which prevents oxidation of the component surfaces. Depending on the process gas, material and laser parameters, the joining process is often determined by pure heat conduction, and in deep welding applications by the keyhole effect.
