Fusion in arc welding [PDF]

open access: possibleProceedings 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

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.

Automation of arc welding

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 ...

Plasma Arc Welding

1993
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 ...
