摘　　要：文章针对钼镧合金材料,进行了焊接试验方案的设计,详述了焊接试验过程,采用手工氩弧焊对钼镧合金管进行焊接试验,并对焊缝进行了渗透检测和氦检漏试验。通过试验,得出了钼镧合金的焊接工艺参数,实现了钼镧合金管道焊接成型,对于钼镧合金材料的焊接成型具有一定的借鉴意义。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.
