The Physics of Welding
TLDR
In this paper, the authors describe electric arc welding, high energy density welding, and future developments of welding processes, and discuss the benefits of better understanding of the physics of welding.Abstract:
Greater understanding of the physics of welding is leading to improved application and control of welding processes. Further gains in welding productivity could follow. Electric arc welding, high energy density welding and future developments are describedread more

Consolidation phenomena in laser and powder-bed based layered manufacturing
TL;DR: In this article, the authors describe which types of laser-induced consolidation can be applied to what type of material, and demonstrate that although SLS/SLM can process polymers, metals, ceramics and composites, quite some limitations and problems cause the palette of applicable materials still to be limited.

Heat and mass transfer in gas metal arc welding. Part II: The metal
J. Hu,Hai-Lung Tsai +1 more
TL;DR: In this paper, a unified comprehensive model was developed to simulate the transport phenomena occurring during the gas metal arc welding process, where an interactive coupling between arc plasma; melting of the electrode; droplet formation, detachment, transfer, and impingement onto the workpiece; and weld pool dynamics all were considered.

A model of deep penetration laser welding based on calculation of the keyhole profile
TL;DR: In this article, a model describing the process of deep-penetration laser welding has been developed by calculating the keyhole profile using a point-by-point determination of the energy balance at the key hole wall.

Experimental Investigation of the Forces Acting on a Drop of Weld Metal The mass of weld metal droplets during globular transfer is measured as a function of electric current and gas flow
H. Waszink,L. H. J. Graat +1 more
TL;DR: In this paper, the drop mass was measured as a function of the gas flow rate and the electric current, and various forces acting on a drop at the point of detachment were derived from the measured data.
Instability of a conducting fluid cylinder in the presence of an axial current, a longitudinal magnetic field and a coaxial conducting cylinder
TL;DR: In this paper, the stability of an infinitely long, inviscid, incompressible fluid cylinder of finite electrical conductivity in the presence of an axial current was investigated, and it was shown that there exists a critical product of axial currents and longitudinal magnetic fields which determines whether the m = 0 mode or the m= 1 mode will be manifested first in the instabilities.
