The operator's dexterity has a real influence upon laser welding quality but this can be reduced when the choice of welding parameters has been optimized. It is possible to avoid the empiric choice of ...

GWEIKE introduces a portable laser welding machine and multifunction M-Series system to help manufacturers improve ...

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 ...

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 ...

The NREL report assesses the potential of replacing plastic polymer connectors with glass-to-glass laser welding. Image: NREL The US Department of Energy’s (DOE’s) National Renewable Energy Laboratory ...

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 ...

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 ...

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 ...

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 ...

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 ...
