A fabricator that needs to weld thick plate in as few passes as possible often will turn to submerged arc welding (SAW), a ...

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 ...

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 ...

U.K.-based Cambridge Vacuum Engineering, a producer of advanced welding technologies, has installed a laser-in-vacuum welding ...

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 ...

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 ...

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 ...

As with traditional welding techniques, materials are melted in the weld zone, although laser-based techniques use quicker heating and cooling cycles (Figure 1). These rapid thermal cycles are a ...

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 ...

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 ...
