Abstract: This paper presents the design of a welding test plan for molybdenum-lanthanum alloy materials, detailing the welding test process. Manual tungsten inert gas welding was used to weld molybdenum-lanthanum alloy tubes, and the welds were inspected using dye penetrant testing and helium leak testing. Through the tests, the welding process parameters for molybdenum-lanthanum alloys were obtained, achieving the welding and forming of molybdenum-lanthanum alloy pipes, which has certain reference significance for the welding and forming of molybdenum-lanthanum alloy materials.
