Deformation and Microstructural Analysis of Fiber Laser and TIG Welding of Thin Ti6Al4V Sheet by Coordinate Measurement Machine (CMM)
Öz
This paper
reports on a study to compare the mechanical and deformation properties of
Ti6Al4V titanium alloy joints between a pulsed fiber laser source and a
tungsten inert gas (TIG) welding. Ti6Al4V alloy sheets - 0.8 mm
thick-deformation modifications were investigated via a 3D laser scanner
integrated to a portable-arm Coordinate Measurement Machine (CMM) and PC-DMIS
software. Deformation pattern, residual distortions, weld geometry,
microstructure and microhardnes properties of the joints produced with fiber
laser source and tungsten inert gas welding were compared. Compared with the
TIG, the welded by fiber laser has narrow heat affected zone (HAZ), small
overall residual distortion, fine microstructure, high Vickers hardness. It can be concluded that fiber laser welding
is more suitable for welding the thin Ti6Al4V titanium alloy plate than TIG
welding; due to the small beam focus characteristics of fiber lasers enabiling
deep penetration welding.
