Impact Tensile Strength of Laser Welded Butt Joint of Steel Sheets for Vehicles

open access: yesJournal of the Society of Materials Science, Japan, 2005
The present study is concerned with the static and dynamic characteristics of laser welded joints related to the tailored blanks technique for vehicles. Three kinds of laser welded butt joints made of different steel sheets for vehicles, a mild steel HR270, high tensile strength steels HR590 and HR780, were used in the static and impact tensile tests ...

Investigating impact of zinc vapor jet on keyhole dynamics and liquid ejection from molten pool during remote laser welding of zinc-coated steel in zero-gap lap joint configuration

open access: yesProcedia CIRP
When Zn-coated steels are laser welded in a zero part-to-part gap lap joint configuration, highly pressurised Zn vapors are readily produced, generating spatters in the weld.

Influence of Augmentation Compositions and Confinement Layers on Flyer Velocity in Laser Impact Welding

open access: yesMetals
Small-scale impact welding may have several advantages over rivets: the strength can be higher, it can be applied right at the edges in lap joints, and it can be lighter and more easily installed if simple systems can be developed.
