ADAP: Adaptive & Dynamic Arc Padding for predicting seam profiles in Multi-Layer-Multi-Pass robotic welding

open access: yesAI Open
Welding thick metal plates using Multi-Layer-Multi-Pass (MLMP) techniques demands precise control over the weld seam profile as it evolves during the cooling process. In MLMP welding, typically executed with Gas Metal Arc Welding (GMAW) and shielding gas

Flow loss and structure of circular arc blades with different leading edges

open access: yesAdvances in Mechanical Engineering, 2018
Due to much lower cost of development and production, circular arc blades are often applied to axial flow fans. However, compared with NACA 65 profile, circular arc blades have higher losses, which are caused by the formation of separation bubbles or ...

Effect of electrode geometry on maximum arc pressure in gas tungsten arc welding.

open access: yesQUARTERLY JOURNAL OF THE JAPAN WELDING SOCIETY, 1985
Effects of an electrode geometry on the maximum arc pressure at a base metal were investigated in GTA welding.Results obtained are as follows;(1) The pressure increases with a decrease in a vertex angle of an electrode. But at the vertex angle of 45° the pressure has a peak value and then the pressure decreases with the decrease in the angle less than ...

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

open access: yesAdvanced Engineering Materials, EarlyView.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting
