Mechanical Property and Microstructure Analysis of Laser Beam Welded Aluminium (A6061)-Titanium (Ti6Al4V) Dissimilar Sheet Metals

Abstract

Developing vogue in engineering, such as lightweighting, expanded execution, and usefulness builds the utilization of complex material, crossover fabric, and in this way, the requirement for fastening different metals. Al and Ti compounds are generally utilized in the aviation and automobile industry because of their appealing properties, like small density, intense conductivity, superior strength, and solidness. Nonetheless, the fastening of Al and Ti combinations by conventional welding techniques is troublesome because of the development of bulk intermetallic mixes. Laser beam welding is efficient for titanium–aluminium welding, a bigger pretence in aviation, automobile, electronics, and different sectors. In this research, distinct 2 mm thickness A6061 and Ti6Al4V butt seams were created by moving a laser supply on the Ti sheet’s top side. Titanium alloy Ti6Al4V and aluminium amalgam 6061 were effectively joined by laser beam welding. The mechanical and microstructural qualities of the welded joints were assessed. The weld piece displays a blend of fine recrystallized particles of the aluminium compound and titanium compound.
