P. Sadeesh,M. Venkatesh Kannan,V. Rajkumar,P. Avinash,N. Arivazhagan,K. Devendranath Ramkumar,S. Narayanan +6 more
TL;DR: In this article, five different tool designs have been employed to analyse the influence of rotation speed and traverse speed over the microstructural and tensile properties of dissimilar AA2024 and AA6061 aluminium plates of 5mm thickness.
Journal ArticleDOI
Metallurgical and mechanical characterization of dissimilar welds of austenitic stainless steel and super-duplex stainless steel – A comparative study
K. Devendranath Ramkumar,Anshuman Singh,Shubham Raghuvanshi,Ankur Bajpai,Tathagat Solanki,M. Arivarasu,N. Arivazhagan,S. Narayanan +7 more
TL;DR: In this article, the joining of dissimilar combinations of austenitic stainless steel, AISI 316L and super-duplex stainless steel (UNS S32750) by continuous current (CC) and pulsed current (PC) gas tungsten arc welding (GTAW) using ER2553 and ERNiCrMo-3 fillers was examined using both optical and scanning electron microscopy (SEM) techniques.
Journal ArticleDOI
