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 …

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 anode boundary layer in atmospheric pressure arc discharges is studied numerically on
the basis of the hydrodynamic (diffusion) equations for plasma components. The governing …

A 2D computational model of the mixing of multiple metal vapours into a helium arc in gas
tungsten arc welding of stainless steel is presented. The combined diffusion coefficient …

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 process capability of gas metal arc welding (GMAW) processes is mainly determined by
the arc properties and the material transfer. In recent years, numerical methods are being …

The interaction between laser and arc plasma is a central issue in laser-arc hybrid welding.
We report a new interaction phenomenon called laser destabilizing arc dynamics in kilowatt …

Gas metal arc welding (GMAW) processes are characterized by a high number of
simultaneously running physical processes. The process capability is mainly determined by …

Metal transfer frequencies in a gas metal arc welding process with a metal-cored wire were
quantitatively measured for the first time as a function of the CO 2 content (ie, 5, 10, 15, 20 …
