Auxiliary energy-assisted arc welding processes and their modelling, sensing and control
Science and technology of welding and joining, 2021Arc welding processes are still widely used in manufacturing industry. To further improve the arc welding efficiency and the joint quality, secondary energy field/source is usually applied to assist the conventional arc welding process.

Proceedings of the American Institute of Electrical Engineers, 1919 Although welding literature is replete with discussions of applications, little information is available descriptive either of non-destructive inspection methods or of the process of metallic electrode are welding. This paper calls attention to such characteristics as penetration and overlap, peculiar to this process, which facilitate visual inspection

Arc Welding and Hybrid Laser-Arc Welding
2009Laser-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.

Industrial Robot: An International Journal, 1978
Welding is becoming increasingly unacceptable as a manual job and this is causing an acceleration in the trend towards automation. This paper briefly reviews some recent efforts at automating welding processes, including a program in the UK by the National Engineering Laboratory and the Welding Institute, and considers the future progress and effects ...

Abstract Plasma arc welding (PAW) can be defined as a gas-shielded arc welding process where the coalescence of metals is achieved via the heat transferred by an arc that is created between a tungsten electrode and a workpiece. This article discusses the melt-in mode and the keyhole mode of the PAW process, as well as the advantages and ...

AIP Conference Proceedings, 1982
A discussion of the factors controlling the size and shape of the weld fusion zone is presented along with a description of current theories of heat and fluid flow phenomena in the plasma and the molten metal weld pool. Although experimental results confirm that surface tension, plasma jets, and weld pool convection all strongly influence the fusion ...
