Determination of stress concentration factors in offshore wind welded structures through a hybrid experimental and numerical approach [PDF]

open access: yes, 2019
Offshore wind turbine (OWT) monopile support structures generally consist of steel cans connected together through circumferential welding joints. One critical factor to evaluate the localised increase in stresses is the stress concentration factor (SCF)

Variety of microstructure and mechanical properties along the laser impact welded interface

open access: yesScience and Technology of Welding and Joining, 2023
Laser impact welding (LIW) is an attractive technique for thin film dissimilar materials solid-state welding. To understand the mechanism of laser impact welding, the wave character of wavy interfaces, the morphology of intermetallics, the diffusion phenomenon and the hardness along the welding direction were investigated with Scanning Electron ...

Laser welding with side-gas application and its impact on spatter formation and weld seam shape

open access: yesProcedia CIRP, 2020
Abstract Spattering is a quality issue within deep penetration laser welding processes resulting in time-consuming and cost-intensive post-processing. In this study, the formation of unconventional weld shapes, e.g. with bulge formation was observed in a lap-joint, while using a side-gas jet to enlargen the capillary opening.
