Investigation into the effects of laser shock peening as a post treatment to laser impact welding
Materials and Design, 2021 In this work, laser shock peening (or simply laser peening) is investigated for the first time as a post welding treatment for dissimilar foils joined via the fully-mechanical, high-velocity laser impact welding technique. Single and double laser peening shots were applied to laser-impact-welded foils using three different metallic material ...

Investigation on a Novel Laser Impact Spot Welding [PDF]
Metals, 2016 In this paper a novel laser impact spot welding (LISW) method is described, in which a hump was formed on the flyer plate on the intended welding spot location by local pre-forming. When the flyer and base plates were placed together to perform welding, the two plates kept in contact over their entire surfaces except at the hump, where a local air gap ...

Characteristics of Flyer Velocity in Laser Impact Welding
Metals, 2019 The flyer velocity is one of the critical parameters for welding to occur in laser impact welding (LIW) and plays a significant role on the welding mechanism study of LIW. It determines the collision pressure between the flyer and the target, and the standoff working distance.

Promoting austenite formation in laser welding of duplex stainless steel—impact of shielding gas and laser reheating [PDF]
Welding in the World, 2020 AbstractAvoiding low austenite fractions and nitride formation are major challenges in laser welding of duplex stainless steels (DSS). The present research aims at investigating efficient means of promoting austenite formation during autogenous laser welding of DSS without sacrificing productivity.

Impact of laser beam shaping on weld pool and seam geometry in butt-joint welding with filler wire
IOP Conference Series: Materials Science and Engineering, 2023 Abstract Beam shaping offers a promising solution to address various challenges in laser-based processes. This study explores the use of an adaptive beam shaping solution using a deformable mirror for high-power continuous wave lasers. Specifically, the impact of three different elliptical beam shapes on weld pool geometry, weld cross ...

Advanced Engineering Materials, 2014 AbstractCw‐laser weldings at different power, focal position, and welding velocity were performed on hypereutectic spray‐compacted aluminum alloys and AlMg3. Two light‐conducting cables, 0.1 and 0.4 mm in diameter were used. For AlMg3 shrink pores were observed for a broad range of parameters.
