Welding Properties of Titanium Alloys Grade 5

Abstract

Titanium alloys have attractive properties that have been widely used in various fields due to these properties. The biocompatibility of titanium has caused its usages in the pharmaceutical industry. Its good corrosion resistance has resulted in its many applications in petrochemical and marine industries. Meanwhile, the most important and major application of titanium and its alloys can be found in the aerospace industry in a variety of spacecraft, space rockets, and satellites. The most important reason for the widespread use of these alloys in the aerospace industry is the high ratio of strength to their weights. However, the most important factor limiting the usage of titanium and its alloys is its high price. In this chapter, we first introduced titanium and its alloys. Then, according to mainstream of the design, titanium alloy bonding methods and welding problems have been investigated. The purpose of this study is to investigate the processes of arc welding of tungsten electrode-neutral gas with different alloy heat inputs for a titanium alloy of Ti-6Al-4 V and to provide comprehensive welding instructions. So, after introducing the pure commercial titanium properties, we examined the properties, specifications and welding of Ti-6Al-4 V. Given the focus on the mentioned process, the generalities of this welding process have been described.

Influence of Different Filler Metals on the Mechanical and Microstructural Characteristics of Arc-Welded Joints Made of Dissimilar Titanium Alloys

“…GTAW (Gas Tungsten Arc Welding) is based on the creation of a weld bonding by making an electric arc with a non-consumable tungsten electrode and protecting the molten pool through a protective gas stream. Due to the generally low deposition rate of this technique, filler metal can be used as well, added manually or mechanically to the weld area [15].…”

“…GTAW technology, performed in manual mode, is widely used in the motorsport segment to weld components made of titanium alloy [16]. This technique has been known for a long time, and in most cases, the joints are made in special inert gloveboxes in order to prevent the well-known oxidation problems in the weld bead and HAZ adjacent areas [15]. GTAW welding requires careful positioning of the edges but may allow, if properly performed, the achievement of high-quality joints displaying good mechanical strength [17].…”
