The invention discloses a direct-current gas shielded welding machine, a welding control method and device thereof and a storage medium, and the welding control method comprises the steps that in the welding stage, pilot arc current is controlled to be kept as first preset current; in the re-burning stage, the pilot arc current is controlled to be kept as second preset current; wherein the first preset current is larger than the second preset current, the second preset current is larger than 0, the discharging phenomenon of output current reburning can be avoided while the ball eliminating effect can be achieved in the reburning stage, the phenomenon of electric arc howling is avoided, and the experience feeling of a user during welding is improved. 本发明公开了一种直流气保焊机及其焊接控制方法、装置、存储介质，包括：在焊接阶段，控制维弧电流保持为第一预设电流；在返烧阶段，控制维弧电流保持为第二预设电流；其中，第一预设电流大于第二预设电流，且第二预设电流大于0，能够在返烧阶段起到"消球"作用的同时，避免了输出电流复燃的放电现象，避免了电弧啸叫的现象发生，提升了用户焊接时的体验感。
