This article introduces the basic principles of plasma arc welding (PAW) and provides a
survey of the latest research and applications in the field. The PAW process is compared to …

An adaptive model of the heat source in numerical simulation of the keyhole plasma arc
welding (PAW) requires that the model take into consideration the larger aspect ratio of …

Keyhole plasma arc welding achieves much deeper penetration than do all other existing
arc welding processes. Because of its ability to penetrate thicker material, the control of the …

Electron beam welding (EBW) of shrouds in Inconel-713LC low-pressure gas turbine blades
has been associated with cracking in fusion zone (FZ) and heat affected zone (HAZ) leading …

A finite element-based simulation of the plasma arc welding process is presented. The
simulation determines the weld pool's three-dimensional capillary surface shape, the …

Modeling and simulation of fluid flow and heat transfer in keyhole plasma arc welding is of
great significance for optimizing the process parameters, and obtaining deep insight of the …

Welding tests were carried out to join the 16 Mn steel with three different shielding modes,
including no shielding, fully covered Argon gas, and backing jet flow Argon gas. It was found …

A three dimensional transient model has been developed to investigate the fluid flow and
heat transfer in the weld pool with a dynamic-variation keyhole during stationary plasma arc …

Fully penetrated keyhole welding process can be achieved by employing the free burning
arc in Tungsten Inert Gas (TIG). The interaction between the heat source and weld pool …
