METALLURGICAL CHARACTERISTICS OF WELDED TITANIUM ALLOYS

Abstract

Titanium and Aluminium alloys are commonly used in various applications. Welding of the above-mentioned materials is of utmost importance in the engineering industry. A lot of studies have been made to understand the mechanical properties of the materials. During welding, titanium alloys absorb oxygen and nitrogen from the atmosphere easily. It has become necessary to develop unique welding procedures and techniques to control the alpha/beta phase transformations and precipitation reactions responsible for the deleterious weld properties in these materials. This article brings out the salient points concerning the metallurgical characteristics of the welded materials.
