Wire-Feeding Based Additive Manufacturing of the Ti–6Al–4V Alloy. Part I. Microstructure
Успехи физики металлов, 2023 In recent years, metal additive manufacturing (AM), also known as 3D printing, is grown massively in the industry. The ability of AM to build parts directly from the digital representation makes it an excellent alternative compared to traditional ...

Hot-wire Laser Welding of Deep and Wide Gaps
Physics Procedia, 2015 AbstractHeavy section Gas Metal Arc Welding (GMAW) usually requires special edge preparation and several passes. One alternative for increased performance is Laser Arc Hybrid Welding (LAHW). For very thick sheets however, imperfections like root drops or solidification cracks can occur.

Welding Phenomena during Vertical Welding on Thick Steel Plate using Hot-wire Laser Welding Method
QUARTERLY JOURNAL OF THE JAPAN WELDING SOCIETY, 2015 The objective of this research was to develop a single-pass vertical welding process for thick steel plates using hot-wire laser welding to reduce the heat input. A laser diode with a large rectangular beam spot and twin hot-wire feeding system were used.

Metal Waste Dusts from Mechanical Workings – Explosibility Parameters Investigation
Chemical Engineering Transactions, 2018 The reactivity of metal scraps or fine particles, typical residual wastes of mechanical workings, is significantly high to cause violent deflagration when particles disperse in the air in the form of clouds.

Lasers in Manufacturing and Materials Processing, 2022 AbstractCladdings are used to protect areas of components that are exposed to particular chemical, physical or tribological stresses. The aim when developing a cladding process is to achieve a cladding with low waviness in order to reduce the amount of machining required.

Advanced Engineering Materials, EarlyView.This study investigates laser metal deposition of aluminum alloys EN AW‐7075 and EN AW‐5083, using powder blending to compensate zinc and magnesium evaporation. In situ alloying and ex situ alloying with ZnAl12 and AZ91 preserve near‐standard compositions and improve mechanical properties.

Advanced Engineering Materials, EarlyView.It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...
