Elongated cavities during keyhole laser welding

[Display omitted] •Plume direction and keyhole size oscillation correlate.•Vapor plume affects the expansion of the keyhole due to beam oscillations.•The melt surface tension of the keyhole walls prevents the keyhole collapse.•An elongated cavity must not necessarily lead to stable processing.•A new...
