Abstract

The advantage of the usage of titanium alloys in numerous engineering applications have prompted several researchers to explore alternatives to the earlier used traditional joining methods such as resistance welding, electric arc welding, etc. In order to obtain quality and faster means of welding machine components, laser welding has been largely adopted in different manufacturing industries such as aerospace, automotive and chemical industries, due to its numerous advantages such as low heat input, low distortion rate, fast welding speed, and small heat-affected zone (HAZ). Quality laser welding requires optimization of several processing parameters among which are: laser power, welding speed and defocusing distance. This article reviews the impact of these processing parameters on some mechanical properties, such as tensile strength, microstructure and hardness of the welded Ti6Al4V plate as presented in the literature and the future research direction is also presented.
