TL;DR: In this paper, the authors investigated different welding processes such as laser beam, resistance, tungsten inert gas, friction stir, submerged arc, and plasma arc weldings considering the research available in the literature.
Abstract: Duplex stainless steels (DSSs) have many advantages due to the unique structural combination of ferrite and austenite grains. The structural change of these materials is very complex during welding, and it deteriorates the functional properties. This research investigates different welding processes such as laser beam, resistance, tungsten inert gas, friction stir, submerged arc, and plasma arc weldings considering the research available in the literature. The welding mechanism, change of material structure, and control parameters have been analyzed for every welding process. This analysis clearly shows that DSS melts in all most all welding processes, but the thermal cycle and maximum heat input are different. This difference affects the resulting structure and functional properties of the weld significantly.

01 Jun 1988TL;DR: In this article, the authors describe a television monitoring system that consists of at least one camera (10) fastened to the support of a welding machine, interposed on the path of the light rays coming from the welding zone and upstream of a device for converting the light ray into video signals, a filter composed of a plate of ceramic material having light rotatory properties and electrodes disposed in contact with each of the two faces of the plate in accordance with a determined network.
Abstract: The televisual monitoring apparatus incorporates at least one camera (10) fastened to the support of the welding machine. The camera (10) incorporates, interposed on the path of the light rays coming from the welding zone and upstream of a device (22) for conversion of the light rays into video signals, a filter (24) composed of a plate of ceramic material having light rotatory properties and electrodes disposed in contact with each of the two faces of the plate in accordance with a determined network. The monitoring device also incorporates, associated with the camera 10, an electronic video signal analysis and electrode potential control arrangement.
