The state-of-the-art on arc welding research is considered, with unresolved questions and
future directions highlighted. Both diagnostics and modelling are discussed. The focus is on …

An introduction to the main methods used to produce, model and measure thermal plasmas
is provided, with emphasis on the differences between thermal plasmas and other types of …

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 …

A numerical model of the droplet detachment of a gas–metal arc welding process is
presented. The model is based on the volume of fluid method and focuses on the detailed …

The presence of metal vapour in gas–metal arc welding has been shown to have two strong
effects on the arc plasma: a decrease in temperature throughout the arc, and the formation of …

The density gradients and flow characteristics of the gas shield during gas metal arc welding
(GMAW) of DH36, higher strength 'construction steel', were visualised using schlieren …

Gas metal arc welding is indispensable in many fields of industry. In this process, various
kinds of shielding gas are used, and they significantly affect the behaviors of the arc plasma …

Spectroscopic measurements for metal inert gas (MIG) arc plasma have been recently
performed. The studies have reported that the central core of the MIG arc has low …

The metal transfer is a fundamental process in gas metal arc welding, which substantially
determines the shape of the weld seam and strongly influences arc formation and stability. In …

In gas metal arc welding, gases of different compositions are used to produce an arc
plasma, which heats and melts the workpiece. They also protect the workpiece from the …
