Abstract

The welding of Magnesium and Titanium and its alloys has continuously depicted a good challenge for designers and technologists. Ti and Mg alloys, particularly heat-treatable alloys, are difficult to join by fusion fastening techniques. The welding of dissimilar alloy such as Ti (Grade 2) and Mg (AZ91D) Alloy is an important problem during Friction Stir Welding (FSW). In this paper, the influence of Rotation speed (Rpm), Travel Speed (mm/min), Bottom Diameter Tool Pins (mm) and Tool Profiles of Ti and Mg alloy during FSW was investigated by Grey Relational Analysis and Anova was used to work out the foremost important Travel speed and feed rate affecting the Response. The primary and cooperation impact of the information factors on the normal reactions are examined. The expected values and measured values are genuinely close.

Highlights

Friction Stir Welding (FSW) method could be a solid state change of integrity technique thought of to be the many development over the past twenty years that was fictional and valid at the fastening institute (TWI), UK within the year 1991
The tools pin and shoulder area units are useful for warmth generation and material mixture by stirring manufacturing the joint
The character of the Sheet Metal decides the sort of change of integrity method

Summary

Introduction

That has become a viable producing technology of gilded sheet and plate materials for applications in varied industries, together with region, automobile, defence and building This change of integrity technique is energy economical, atmosphere friendly and versatile. A contemporary associate in an atmosphere friendly solid - state change of integrity method wont to be a part of comparatively lighter family of materials, aluminium and its alloys is dealt during this study [1, 2]. Crucial applications of those alloys embrace region, automobile and ship building likewise [3]. Solid-state fastening processes overcome a range of different issues in fusion fastening of aluminium alloys like consistence, segregation, brittle lay to rest gilded formation, and warmth affected zone
