TL;DR: In this article, the stability of a viscous, current-carrying fluid cylinder with surface charge was investigated in the context of metal transfer in arc welding and it was found that viscous effects are negligible while electrostatic effects exert a stabilising influence and may have interesting effects on stability.
Abstract: This paper considers, largely in the context of metal transfer in arc welding, the stability of a viscous, current-carrying fluid cylinder with surface charge. Simple expressions are obtained between the characteristics of instability growth and the dependence of these on 'process parameters'. For liquid metals it is found that viscous effects are negligible while electrostatic effects exert a stabilising influence and may have a number of interesting effects on stability (particularly at low wire currents).

TL;DR: In this paper, the magnetic pulse welding (MPW) is used to drive the primary metal against the target metal sweeping away surface contaminants while forcing intimate metal-tometal contact, thereby producing a solid-state weld.
Abstract: The magnetic pulse welding (MPW) is a cold weld process of conductive metals to the similar or dissimilar material. MPW uses magnetic pressure to drive the primary metal against the target metal sweeping away surface contaminants while forcing intimate metal-tometal contact, thereby producing a solid-state weld. In this paper the MPW method and its application for several aluminium alloy (A1050, A2017, A3004, A5182, A5052, A6016, and A7075) and steel (SPCC) sheets joint were investigated and the process parameters and welding characteristics are reported.

TL;DR: In this paper, a mathematical formulation of the temperature profiles in gas tungsten arc welding (GTAW) arcs and the net heat flux from the welding arc to the weld pool is presented.
Abstract: A mathematical formulation has been developed and computed results are presented describing the temperature profiles in gas tungsten arc welding (GTAW) arcs and, hence, the net heat flux from the welding arc to the weld pool. The formulation consists of the statement of Maxwell's equations, coupled to the Navier-Stokes equations and the differential thermal energy balance equation. The theoretical predictions for the heat flux to the workpiece are in good agreement with experimental measurements — for long arcs. The results of this work provide a fundamental basis for predicting the behavior of arc welding systems from first principles.

TL;DR: In this paper, a virtual reality arc welding system and a computerized eyewear device having a head-up display (HUD) have been discussed for assisting a welder or welding student.
Abstract: Systems and methods to aid a welder or welding student. A system may provide a real-world arc welding system or a virtual reality arc welding system along with a computerized eyewear device having a head-up display (HUD). The computerized eyewear device may be worn by a user under a conventional welding helmet as eye glasses are worn and may wirelessly communicate with a welding power source of a real-world arc welding system or a programmable processor-based subsystem of a virtual reality arc welding system.
