The extra-high-tensile steel D406A was welded by A-TIG experiment. The welding process pacification was groped, and then organization and performance of extra-high-tensile steel D406A A-TIG welding joint were studied. The results show that A-TIG welding deeply increased penetration and obviously improved weld forming. The sensitivity of welding crack of A-TIG is lower than that of the regular TIG, while the comprehensive mechanics performance of the joint is better. The production of shell sample and examination of comprehensive product assessment performance through pressure test and blasting testappa established the foundation for overall promotion application of A-TIG welding in extra-high-tensile steel D406A.
