Application of laser-arc hybrid welding of steel for low-temperature service
(Journal article; Peer reviewed, 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
(Peer reviewed; Journal article, 2020)Wire and arc additive manufacturing (WAAM) of metallic materials is expected to become part of the new industrial revolution. The possibilities for complex designs and superior mechanical properties can in many cases replace ... -
Dry hyperbaric welding of HSLA steel up to 35 bar ambient pressure with CMT arc mode
(Peer reviewed; Journal article, 2019)Hyperbaric welding plays a significant role in subsea pipeline installations and repairs for transport of oil and gas from the offshore field to the market. The effect of ambient pressure, from 1 to 35 bar, on penetration ... -
A fast simulation method for thermal management in wire arc additive manufacturing repair of a thin-walled structure
(Peer reviewed; Journal article, 2024)Ensuring first-time-right on-site repair of critical structures is a key challenge for additive manufacturing (AM)–based repair solutions. Fast thermal simulations are thus needed to plan efficient and error-free AM ... -
Grain refinement of aluminium welds by Ti, TiB2, and TiC filler wire inoculation
(Peer reviewed; Journal article, 2023)A fine-grained fusion zone characterises a tough aluminium weld. To improve the solidification characteristics and refine the grains in aluminium welding, different inoculation particle combinations were introduced to the ... -
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 ... -
Laser beam remelting of stainless steel plate for cladding and comparison with conventional CMT process
(Peer reviewed; Journal article, 2023)Progressing towards circular economy requires smarter and more efficient use of energy and resources. Laser beam can be efficient and flexible tool for melting different metals, commonly used in cladding and additive ... -
Laser-arc hybrid welding of 12- and 15-mm thick structural steel
(Peer reviewed; Journal article, 2020)High-power lasers are very effective in welding of plates thicker than 10 mm due to the keyhole mode. High-power intensity generates a vapor-filled cavity which provides substantial penetration depth. Due to the narrow and ... -
A new method to estimate the residual stresses in additive manufacturing characterized by point heat source
(Peer reviewed; Journal article, 2019)Residual stress in additive manufacturing (AM) is one of the key challenges in terms of structural integrity and finish quality of printed components. Estimating the residual stress distribution on additively manufactured ... -
Root formation and metallurgical challenges in laser beam and laser-arc hybrid welding of thick structural steel
(Peer reviewed; Journal article, 2021)Single-pass laser beam welding (LBW) of steel components with wall thickness of > 10 mm is of high interest due to enhanced productivity. Deep penetration LBW provides excessive hardness and certain quality issues such as ... -
Wire arc additive manufacturing of AA5183 with TiC nanoparticles
(Peer reviewed; Journal article, 2021)Aluminium alloys processed by wire arc additive manufacturing (WAAM) exhibit a relatively coarse microstructure with a columnar morphology. A powerful measure to refine the microstructure and to enhance mechanical properties ...
