Batman Energy Summit, 30 June-02 July 2022, Batman, Turkey.https://hdl.handle.net/20.500.12402/4413Invar alloys are materials used in aviation and aerospace industries to make precision components and test equipment due to their excellent coefficient of thermal expansion. Therefore, the diversity of the joining methods of these materials and their joint strength have gained importance. In the presented study, the optimum welding parameters required for the minimum use of energy consumed during MIG welding of Invar alloy materials and for the joints to have the highest tensile strength were investigated. The lowest tensile strength was found to be 375 MPa at 15 mm/s welding speed and 6 mm/s wire feeding speed, and the highest tensile strength was 405 MPa at 20 mm/s welding speed and 18 mm/s wire feed. It has been understood that the power consumed for joining Invar alloy bars generally increases in direct proportion to the parameter increases up to 20 mm/s welding speed. It was observed that the lowest consumed power value was 1.61 kW with 15 mm/s welding speed and 6 mm/s wire feeding speed, while the highest consumed power value was 3.93 kW with 25mm/s welding speed and 18 mm/s wire feeding speed. It has been understood that an average of 38% energy savings can be achieved thanks to the optimum parameters obtained.eninfo:eu-repo/semantics/openAccessEnergy SavingInvar 36Invar AlloyMIG WeldingTensile StrengthConference Object
