Laser Welding

Laser welding joins thin metals and compatible polymers with a small, controlled heat input — conduction or keyhole welds in metals, transmission welds in polymers. It suits miniaturized medical and electronic assemblies where a contact process would distort or contaminate the part.

How it works

A focused beam melts a controlled volume at the joint, and the material fuses as it cools. In polymer transmission welding, the beam passes through one part and the interface with the second part absorbs it. Pulse shaping controls penetration and the heat-affected zone.

Process envelope

Joint typesSeam, spot, transmission (polymer)
MaterialsStainless, nitinol, titanium, thin foils; compatible polymers
Heat-affected zoneMinimal; validated per joint
FillerNone

Welds that fit the scan field run on ExactCore™; seam work that needs full-bed repeatability runs on ExactPro™.

Micro-joining is a process people are rightly cautious about. So it starts in the lab, with your parts and your joint geometry. You get a written report before anyone talks about a machine.
