Figure 1. Various test samples that have been laser welded in an applications lab (a) and a low-density polyethylene fluid container welded with a diode laser system (b). Direct welding of plastics is ...

Industrial lasers are used to process engineering plastics across many markets. Some examples of the common processes are shown in Figure 1, including laser marking, cutting, and welding.

Non-contact laser welding offers several advantages when it comes to joining one plastic part to another. It works on the principle of partial transmission which lets a laser’s light travel through ...

Several factors point to a major acceleration of laser welding as a method of joining plastics, particularly for electronics enclosures: High equipment and materials costs, however, remain a concern, ...
