1. State of the art in friction stir welding and ultrasonic vibration-assisted friction stir welding of similar/dissimilar aluminum alloys

Satish S Chinchanikar; Vaibhav S Gaikwad

Articles in Press, Accepted Manuscript, Available Online from 06 March 2021


  Researchers worked on many facets of joining of similar/dissimilar aluminum alloys using different joining techniques and came up with their own recommendations. Friction Stir Welding (FSW) is widely preferred for joining aluminum alloys being an economical alternative to produce high-quality welds. ...  Read More

2. Optimization of gas metal arcwelding parameters of SS304 austenitic steel by Taguchi –Grey relational analysis

Saadat Ali Rizvi; S P Tewari

Volume 7, Issue 2 , Winter and Spring 2018, , Pages 189-198


  This study investigated the optimization of three welding parameters (wire feed speed, arc voltage, and shielding gas flow rate) for SS 304H by using Taguchi based Grey relational analysis. In this research work, pure argon was used as shielding gas. Numbers of trials were performed as per ...  Read More

M. Azizpour; M. Ghoreishi; A. Khorram

Volume 4, Issue 2 , Winter and Spring 2015, , Pages 145-154


  This paper was aimed to report the 3D finite element analysis simulation of laser welding process of Ti6Al4V 1.7 mm sheets in butt joint in order to predict the temperature distribution, hardness, and weld geometry. The butt-joint welds were made using CO2 laser with the maximum power of 2.2 kW in the ...  Read More

4. Dissimilar friction stir lap welding of Al-Mg to CuZn34: Application of grey relational analysis for optimizing process parameters

Saman Khalilpourazary; Reza Abdi Behnagh; Ramezanali Mahdavinejad; Nasib Payam

Volume 4, Issue 1 , Summer and Autumn 2014, , Pages 81-88


  This study focused on the optimization of Al—Mg to CuZn34 friction stir lap welding (FSLW) process for optimal combination of rotational and traverse speeds in order to yield favorable fracture load using Grey relational analysis (GRA). First, the degree of freedom was calculated for the system. ...  Read More

5. Effect of welding parameters on pitting corrosion rate of pulsed current micro plasma arc welded AISI 304L sheets in 1N HCl

Kondapalli Siva Prasad; Chalamalasetti Srinivasa Rao; Damera Nageswara Rao

Volume 3, Issue 1 , Summer and Autumn 2013, , Pages 1-11


  Austenitic stainless steel sheets have gained wide acceptance in the fabrication of components, which require high temperature resistance and corrosion resistance such as metal bellows used in expansion joints in aircraft, aerospace and petroleum industries. In the case of single pass welding of thinner ...  Read More
