What is Laser Welding?

Laser welding of plastic parts has established itself as a robust, flexible and precise joining process. It enables highly efficient and flexible assembly from a small-scale production of parts with complex geometries to a high volume industrial manufacturing, where it can be easily integrated into automation lines. The plastic laser welding process uses a laser beam to melt the plastic in the joint area by delivering a controlled amount of energy to a precise location. This level of precision in controlling the heat input is based on the ease of adjusting the beam size and the range of methods available for precise positioning and moving the beam.

Contour Welding

In the case of contour welding, a focused laser beam moves sequentially along the welding seam, melting it locally. Due to the geometric conditions, the welding volume remains small and so the melt does not escape. Relative movement is achieved through the motion of the component, the laser, or a combination of the two.

Quasi Simultaneous

Two scanner mirrors deflect the laser spot and guide it along the welding contour at a very high speed. The joining surface is traversed several times per second, whereby the laser beam effectively heats and plasticizes the entire welding seam at the same time. Part tolerances can be melted off forming a welding bead, as both joining parts are pressed together during the welding process.
