Enhancing the fastness characteristics of weld‐dyed cotton and recycled nylon 6,6 fabrics via sodium alginate and titanium dioxide

Coloration Technology, EarlyView.
Abstract This study investigates a sustainable dyeing and finishing strategy for recycled nylon 6,6 and organic cotton fabrics dyed with weld. Following meta‐mordant dyeing using alum under Natural Organic Dye Standard (NODS)‐compliant conditions, the fabrics were subjected to functional finishing with titanium dioxide as a multifunctional ...

Correlation between Arc Phenomena and Welding Parameters in Submerged-Arc Welding

Journal of the Japan Welding Society, 1981
In submerged arc welding, the direction of arc column and the position of molten metal in the crater have been examined using a X-ray image intensifier TV system in order to regulate weld bead shape by controlling welding parameters.Arcs are classified into the open and buried arcs depending on the position of electrode tip to the plate surface.

Axial and Biaxial Fatigue Behavior of 6061‐T651 Cold Metal Transfer Welded Joints

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Lightweight aluminum structures in transportation systems are increasingly exposed to complex service loading, yet the fatigue performance of welded joints is still predominantly assessed using uniaxial data. In this work, the axial and biaxial fatigue behavior of 6061‐T651 aluminum alloy joints produced by cold metal transfer (CMT) welding is

Use of audible sound for on-line monitoring of gas metal arc welding process [PDF]

Metalurgija, 2008
In this paper sound generated during the gas-metal arc welding process was studded. Experimental analyses of the acoustic signals have shown that there are two main noise-generating mechanisms, first having impulse form is arc extinction and arc ignition;

Inter‐disciplinary perspectives on sustainability in machinery manufacturing

International Journal of Management Reviews, EarlyView.
Abstract Perspectives on economic, social and environmental sustainability in machinery manufacturing are changing. These are predominantly driven by increased consumer, firm and public knowledge on the importance of sustainability and the role that machinery manufacturers can play to achieve sustainability outcomes.

Metallurgical characteristics of armour steel welded joints used for combat vehicle construction

Defence Technology, 2018
Austenitic stainless steel (ASS) and High nickel steel (HNS) welding consumables are being used for welding Q&T steels, as they have higher solubility for hydrogen in austenitic phase, to avoid hydrogen induced cracking (HIC) but they are very expensive.

When biology meets materials science – Interdisciplinary applications of electron microscopy

Journal of Microscopy, EarlyView.
Abstract Research at the interface between biology and materials science creates challenges for electron microscopists. Everything from the sample preparation to the choice of imaging and analytical techniques and the interpretation of the resulting data refuses to sit comfortably within the domain of one discipline or the other.
