Effects of Contaminations on Electric Arc Behavior and Occurrence of Defects in Wire Arc Additive Manufacturing of 316L-Si Stainless Steel

Metals
Additive Manufacturing is a manufacturing process that consists of obtaining a three-dimensional object from the deposition of material layer by layer, unlike conventional subtractive manufacturing methods.

Wire arc additive manufacturing of porous metal using welding pore defects

Materials & Design, 2023
A novel wire arc additive manufacturing process is proposed to produce porous metal (PM). The innovation is to convert harmful welding pore defects into a beneficial structure of PM, and then the PM parts can be additive manufactured layer by layer.

Microstructure and Mechanical Properties of Wire Arc Additive Manufactured Zl205a Alloy

SSRN Electronic Journal, 2022
The evolution of grain structure, precipitates and mechanical properties of the ZL205A alloy prepared by wire arc additive manufacturing were investigated. The results show that the as-deposited alloy consists of equiaxed and columnar grains in the bottom region. As the deposition height increases, the alloy mainly consists of equiaxed grains.

Static Properties and Fatigue Strength of Wire Arc Additive Manufactured 316L

2022 7th National Scientific Conference on Applying New Technology in Green Buildings (ATiGB), 2022
Abstract The use of direct energy deposition (DED) has become much more common recently and in the future the DED technology will be used even more widely. Wire arc additive manufacturing (WAAM) technology has become much more widespread because it can be done cost-effectively with normal cold metal transfer (CMT) welding equipment.

Influence of an Argon/Silane Atmosphere on the Temperature of a Thermal Plasma

Advanced Engineering Materials, EarlyView.
The influence of a silane‐doped argon atmosphere on the chemical composition and temperature of a thermal nontransferring argon plasma is investigated using optical emission spectroscopy. As a result of the high amount of free electrons resulting from the stepwise ionization and dissociation of the silane molecule, even a silane addition of 0.01 vol ...
