Arc Welding and Hybrid Laser-Arc Welding

2009
Laser-arc hybrid welding has developed into a viable industrial technology in recent years, and is attracting increasing commercial interest. The physics of the underlying interactions is quite complex. In order to explore the relationships involved, it is useful to consider important aspects of laser and arc welding separately.

Analysis of the energy propagation in the keyhole plasma arc welding using a novel fully coupled plasma arc-keyhole-weld pool model

International Journal of Heat and Mass Transfer, 2019
The distribution of the energy in the keyhole plasma arc welding process has significant effect on the final weld quality. In this study, a novel fully coupled plasma arc-keyhole-weld pool model is built to study the energy propagation in the keyhole ...

The surface depression and temperatures in molten pool with pulsed arc welding

Journal of Manufacturing Processes, 2019
Melting fluids are a key factor during the welding metallurgical process of Ti-6Al-4V that determines the solidification and microstructures of welds. The surface of molten pool is the interface between the arc plasma and fluid, which reflects the effect

Electric welding by the carbon arc

Journal of the A.I.E.E., 1930
This paper discusses the butt welding of steel sheets by the carbon arc process. It explains first that autogenous welding is divided into two main classes, viz., gas and electric; that electric arc welding is divided into two classes, viz., metallic and carbon arc. Gas and metallic arc welding in general require beveling of plates for butt welds while

Arc welding of grooved rails – manual metal arc welding versus flux cored arc welding

2012
Experience collected by the members of the Chair for Railways during 15 years of the supervision of re/construction of tram tracks in the Croatian capital Zagreb and city of Osijek revealed that the largest percentage of local rail damage occurs at the welded rail joints.

Measurements of Welding Arcs and Plasma Arcs

1991
Welding and plasma arcs are among the most powerful emitters of optical radiation. The temperature of welding and plasma arcs is extremely high and the ultraviolet output is therefore potentially hazardous. As is well known the visible radiation emitted by these arcs is blinding, and several cases of severe retinal burns are known to have caused ...
