Development of the Working Techniques Required to Apply Friction Stir Welding in Liquid Environment

Abstract:

Submerged Friction Stir Welding (SFSW) is a topic of international interest, with research aiming at the possibilities of application to a wide range of materials, to achieve better results compared to other welding techniques (e.g. conventional welding, FSW welding in ambient air environment), as well as avoiding overheating of welding tools and welding devices during the welding process.SFSW welding is also a topic of interest within ISIM Timisoara, the paper presenting own contributions to the development of the working technique required for the application of SFSW welding. Variants of technical solutions designed and made by ISIM for the application of the SFSW process are presented, these could be integrated, as appropriate, on the FSW welding machine from the endowment of ISIM, to carry out preliminary experiments of SFSW welding. The preliminary results show that the constructive solutions for the application of liquid working environment to FSW welding are functional and can be used for experimental programs of SFSW welding for different metallic materials.
