An introduction to laser welding

A brief introduction to laser welding, the technologies involved, and the advantages it offers over other joining methods

Researchers at IFSW’s x-ray facility will study dynamic beam lasers to better understand the impact of laser beam shape, shape frequency, and shape sequencing on keyhole stability, weld quality, and microstructure. (Image: Civan Lasers)

Researchers study melt pool dynamics using high-speed x-ray diagnostics

The researchers will view inside the melt pool during laser welding to better understand the origin of defects such as pores, spatter, and cracking

Hydrogen fuel cells could provide a suitable alternative to plug-in electric HGVs, where the weight of the battery could prove to be an issue. (Image: Shutterstock/Audeo und werbung)

Dynamic beam control takes on fuel cell welding challenges

New laser technology could help make hydrogen-powered vehicles commercially viable, David Stuart finds
