LASER PRECISION WELDING - HIGH STRENGTH JOINTS WITHOUT ADDITIONAL MATERIALS
Laser precision welding is a modern joining process and is used when conventional welding processes cannot meet the requirements. Due to the highly focussed laser beam, very fine welding spots or seams with high strength and tightness are possible.
Due to the high power density in the focus, the very short process times and the precisely adjustable energy input via the laser parameters, even conventionally difficult-to-weld material combinations can be successfully joined with the laser.
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.

Micrometer-precise, high-strength joints

With or without additional material

Minimal heat input

No structural changes in the material

Suitable for special material combinations
Scope of Service
When conventional welding methods reach their limits, we can help you with our laser systems and our contract manufacturing. For 2D and 3D components as well as for cylindrical and tubular precision components, different welding seams and geometries with up to 2 mm welding depths can be realized using the following processes:
Spot welding
Seam welding
What laser equipment is finally used depends on the geometry of your components and your specific requirements.
