Metal vapour is formed in arc welding processes by the evaporation of molten metal in the
weld pool, and in the case of gas–metal arc welding, in the wire electrode and droplets. The …

Current fabrication of nanomaterials is facing the following two challenges: high selectivity
toward specific chemical compositions or morphologies and their scalable production. This …

This study investigates the effect of shielding gases (namely, 98% Ar-2% CO 2 and 96% Ar-
3% CO 2–1% O 2) on the bi-metallic wire arc additive manufacturing (WAAM) of creep …

The thermal or process efficiency in gas metal arc welding (GMAW) is a crucial input to
numerical models of the process and requires the use of an accurate welding calorimeter. In …

The most advanced numerical models of gas–metal arc welding (GMAW) neglect
vaporization of metal, and assume an argon atmosphere for the arc region, as is also …

Thermal plasma processes are widely used in industrial applications, including arc welding,
