Abstract Ti-1Al-8V-5Fe (Ti-185) and other Fe containing β-Ti alloys are attractive because of
their high strength and low cost. These alloys, however, cannot be produced through ingot …

Varied-thickness deposition faces the challenge of simultaneously achieving the expected
width and maintaining a flat layer. Herein, the current and wire feed speed (WFS) were …

To enhance the reliability of aluminum alloy welding quality, a novel Pulsed Plasma Gas
Variable Polarity Plasma Arc Welding (PPG-VPPAW) system is proposed. This system …

A novel soft variable polarity plasma arc has been proposed to solve the problems in
horizontal welding of aluminium alloys (in 2G position). It is defined as an arc with reduced …

A 3D multi-scale and multi-physics numerical model has been developed and validated to
predict the occurrence of hot cracking during fusion welding of Al-Mg-Si alloys. The new …

This study considered the effect of shielding gas parameters (composition, supply method
and flow rate) on the post-weld thermal properties (thermal expansion, specific heat …

Soft variable polarity plasma arc welding technology has been proposed to solve the
problems in horizontal position welding for aluminium alloys. Arc thermal field shape, arc …

Tungsten inert gas (TIG) welding of austenitic stainless steels is a critical process used in
industries. Several properties of the welds must be controlled depending on the application …

The alternating shielding gas technique is a method of achieving transient arc
characteristics during arc welding; however the complex flow that occurs through its use has …

The influence of alternating shielding gas on fusion characteristics and weld metal
characteristics was examined using a solid wire electrode on SA515Gr 70 carbon steel …
