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 ...

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 ...

Researchers discuss an ambitious project to understand the basic principles of laser welding better than ever before. On its surface, the work is deceptively simple: Shoot a high-power laser beam onto ...

DuPont Engineering Polymers, Wilmington Del. (www.plastics.dupont.com), for example, offers a wide range of suitable materials for laser welding. It's relatively easy to produce strong welds with ...

Medical devices use a variety of metal components that are often welded to form a secure and permanent bond. Options available for welding processes are limited because of certain constraints such as ...

Laser welding of plastic is quick, precise, and generates little waste, but it does have its limitations. The process involves shining a laser beam through the edge of an upper sheet of plastic and ...

What makes a good construction material? There are many requirements, but one is the ability to efficiently connect different parts. Steel is almost the perfect example: you can join steel with ...

Everybody likes 3D printing, right? But it’s slow compared to 2D laser cutting. If only there were a way to combine multiple 2D slices into a 3D model. OK, we know that you’re already doing it by hand ...

On its surface, the work is deceptively simple: Shoot a high-power laser beam onto a piece of metal for a fraction of a second and see what happens. But researchers say the physics of laser welding is ...
