A deep learning approach for anomaly detection based on SAE and LSTM in mechanical equipment
(Journal article; Peer reviewed, 2019)Anomaly in mechanical systems may cause equipment to break down with serious safety, environment, and economic impact. Since many mechanical equipment usually operates under tough working environments, which makes them ... -
A new method for assessing anisotropy in fused deposition modeled parts using computed tomography data
(Journal article; Peer reviewed, 2019)Voids in fused deposition modeled (FDM) parts are assumed to be a key driver for their anisotropic behavior. However, these assumptions are based on investigations of voids using only 2D data (microscopy images). This paper ... -
Application of laser-arc hybrid welding of steel for low-temperature service
(Peer reviewed; Journal article, 2019)Laser-arc hybrid welding (LAHW) is more often used in shipbuilding and oil and gas industries in recent years. Its popularity arises due to many advantages compared to conventional arc welding processes. The laser beam ... -
Comparative study of eutectic Al-Si alloys manufactured by WAAM and casting

Exploring the hybrid metal extrusion and bonding process for butt welding of Al–Mg–Si alloys
(Journal article; Peer reviewed, 2018)The hybrid metal extrusion and bonding (HYB) process is a new solid-state joining technique developed for aluminum alloys. By the use of filler material addition and plastic deformation sound joints can be produced at ... -
First demonstration of a new additive manufacturing process based on metal extrusion and solid-state bonding
(Journal article; Peer reviewed, 2019)In this paper, a new additive manufacturing (AM) process based on extrusion and solid-state bonding is presented. The process uses metal feedstock wire which is processed in a continuous rotary extruder in order to disperse ... -
Generation of rule-adhering robot programs for aluminium welding automatically from CAD
(Peer reviewed; Journal article, 2023)This paper presents a method to automatically generate robot welding programs from CAD to address the ever-constant demand for product customisation. Furthermore, to ensure that proper welding operations and structural ... -
An investigation of the anisotropic properties of heat-treated maraging steel grade 300 processed by laser powder bed fusion
(Peer reviewed; Journal article, 2021)In order to explore the possibilities enabled by laser beam powder bed fusion of metals (PBF-LB/M), reliable material models are necessary to optimize designs with respect to weight and stiffness. Due to the unique processing ... -
Modelling time efficiency of cobot-supported kit preparation
(Peer reviewed; Journal article, 2020)Kitting – meaning to supply assembly with components in presorted kits – is widely seen as beneficial for assembly quality and efficiency when there is a multitude of component variants. However, the process by which kits ... -
A new mechanical calibration strategy for U-channel extrusions
(Peer reviewed; Journal article, 2020)The extrusion process of aluminum profiles introduces dimensional variations commonly exceeding the dimensional tolerance requirements for fit-up and assembly when using automated welding processes in the automotive industry. ... -
