Impact Analysis of Welding Sequence to Reduce Weld Deformation in Aluminum Hulls

Journal of Marine Science and Engineering
Aluminum hulls, which are preferred in the marine industry due to their durability, corrosion resistance, and lightweight properties, face serious challenges due to thermal deformation during welding. This study aims to predict and minimize transverse deformations due to welding sequences for a transverse model in the lower part of an aluminum hull. To

Cathodic Cage Plasma Deposition of Nanostructured Cu–Fe–Se Coatings on Poly(methyl Methacrylate)

Advanced Engineering Materials, EarlyView.
Nanostructured Cu–Fe–Se coatings are deposited on PMMA by a modified cathodic cage plasma process, enabling low‐temperature deposition on polymer substrates. A transition from discontinuous to compact morphology is observed with temperature, with optimal properties at 200°C, where improved CuFeSe2‐type bonding, lowest sheet resistance, and favorable ...

Impact of Welding Current on Weld Formation in Variable Polarity Plasma Arc Welding: A Numerical and Experimental Analysis

Materials
The characteristics of a variable polarity plasma arc (VPPA) and the keyhole behavior significantly influence weld formation. This study investigates the impact mechanism of welding current on weld formation by examining both arc thermal-force output and keyhole behavior through a combination of numerical analysis and experimental methods.
