Spot- and seam welding of metals with lasers is precise and allows joining of very small welding spots and finest welding seams of miniaturized, electrical components. By using galvo scanning heads, the process is very quickly and flexibly adjustable. Integrated image processing systems allow the reliable automated processing even with position tolerances of the components.
The laser transmission welding of plastics completely displaces the connection into the inner of the join partner, works with minimal heat input and leaves the surfaces in perfect condition. Therefore, also sensitive components, such as in sensors, can be welded gas-proof. Competing methods like the bonding of plastics require surface treatment and work with organic dissolvers. Sometimes, like the welding with heating elements or hot air, they are cheap, but dull and soon wore out.
