Abstract

Parameter optimization is the active subject of research, and in this current work the ferrite number and gas tungsten arc (GTA) welding SS. Filler material. Models have been developed by welding SD316L slab with NiTinol wire (shape memory alloy) as a filler material by conducting experiments using three-factor, three level factorial designs. Tests have been conducted for various models at UTM and the results are scheduled. The final models were upgraded using the design expert method. It can be seen from the investigation that the interactive effect of the process parameters has a significant effect on the tensile strength and the ferrite number.

Summary

Introduction

Case tungsten arc welding (GTAW), often referred to as TIG welding, has become a popular choice of welding processes when high quality, precision welding is required. Stiffness and other properties of nitrite can be controlled by chemical composition, heat treatment and temperature [3] and Shabalovskaya et al, [4] Explored bio-compatibility and found its application in the form of stents and guide wires in medical devices. Li et al [5,6] conducted laser brazing of NiTi SMA and stainless steel with Ag-based filler metal, Capacitor discharge welding, microplasma arc welding done by Qiu [7] and laser welding done by Li [8] of NiTi SMA to stainless steel wires were investigated. An attempt has been made to explore the precision welding process of TIGs with their tensile properties and ferrite number as a filler material for welding steel 316L slab with nitinol wire
