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.

“…[1][2][3] The α + β phase Ti-6Al-4V alloy is widely used due to the high strength, and the possibility of varying mechanical and physical properties which can be offered by control of the microstructural development during thermomechanical processing. 4,5 However, the processing method of titanium alloys is still challenging, especially for the thick plates, due to their high strength, large viscosity and poor thermal conductivity. As the application of thick titanium alloy plates in pressure vessels and large chemical equipments is increasing, it is necessary to develop effective technologies to process thick titanium alloys.…”

Narrow-gap tungsten inert gas welding with in situ protective system is applied to 78-mm-thick Ti–6Al–4V alloy. The martensite basketweave microstructure is formed in fusion zone (FZ), and heat-affected zone (HAZ) near FZ consists of acicular martensite and a small portion of primary alpha phase. The HAZ near base metal (BM) consists of primary alpha and transformed beta phase. Microhardness values of FZ and HAZ are relatively higher, and peak values appear at HAZ near FZ. The mechanical heterogeneity is dependent on variation of beta phase and martensite, which in turn depend on specific thermal cycle(s). The average tensile strength reaches 783.3 MPa and is 91.2% of BM, which appears in the middle of the weld with orthogonal martensites.

“…Generally the gas tungsten arc welding-Autogenous (GTAWA) is used to weld titanium and its alloys [4][5][6][7][8]. The argon gas is used as shield the weld pool from contamination and to prevent hydrogen embrittlement [9][10][11][12][13][14][15][16][17][18][19]. Nowadays high-energy intense welding techniques like LASER beam welding are also used to implement critical applications [20][21][22].…”

The titanium alloys are widely used in aerospace, highly corrosive environments and prosthetics. Among the titanium alloys, Ti6Al4V is used much, due to its high strength to weight ratio and its ability to easy fabrication. The Ti6Al4V has good weldability, but it is susceptible to hydrogen embrittlement. The welding technique used for fabricating the Ti6Al4V makes a significant effect in the microstructure of the weldments. The microstructural changes are significant, since it determines the properties, behaviour and reliability of the welded joints. This investigation was done to determine the changes in the microstructure of butt joints prepared from 3 mm rolled plates. The welding was done using Gas-TungstenArc Welding (GTAW) and Laser Beam Welding (LBW) processes. In both the processes argon with 99.9% purity was used for shielding, to avoid any contamination. In this investigation it was found that the Laser Beam Welding produced weldments with smaller heat affected zone and associated high hardness.
