Fiber laser-GMA hybrid welding of commercially pure titanium
AbstractFiber laser-gas metal arc (GMA) hybrid welding process was introduced to weld of commercially pure titanium (CP-Ti) of 1.5mm in thickness. Effect of welding parameters on the hybrid weldability was investigated concerning the bead shape, hardness, tensile properties and microstructures of welded joints compared with those of a fiber laser welded joint. As a result, fiber laser-GMA hybrid welding process has been shown to weld of CP-Ti sheets in 1.5mm thickness at speeds of up to 9m/min. In addition, fiber laser-GMA hybrid welding produces higher Vickers hardness and tensile strength than that of the base metal. Compared with the laser welded joints, it is obvious that the hybrid welded joints have better combination of strength and ductility.
