Gap Bridging

CO2 laser - Metal Inert Gas (MIG) hybrid welding process was investigated in the butt welding of Ti-6Al-4V titanium alloy sheets of 3.0mm in thickness. Using a Design of Experiment (DoE) approach, bead on plate tests were planned with the aim to analyze the effect of laser and laser-MIG welding parameters on the bead shape, hardness profiles in the weld cross section and welding efficiency. Butt welds performed in correspondence of the bead on plate working conditions which assure the complete penetration of the samples, the absence of undercuts and the maximum welding efficiency, confirm the results of the bead on plate tests and highlights the gap bridging ability of the hybrid welding process.

Set Up

Against the T-joint connection problem, the CO2 laser and TIG arc hybrid welding Experiment Platform is set up. The implemented T-joint titanium alloy connection test adopts a novel fashion that while welding the upside of the sheet the bilateral back formed well. The preferred solution is presented based on studies such as arrangement of heat source, wire feeding, shielding gas selection and gap adaptability. The results reveal that the technology provides a new efficient method for the T-joint titanium alloy connection.
