The invention relates to the technical field of aluminum alloy manufacturing, and particularly discloses a 2A12 aluminum alloy oxygen production rack and a welding process thereof. The oxygen generation frame adopts 2A12 aluminum alloy, has high frame strength, controls the temperature of a molten pool in a lower range in the welding process, has higher welding speed, can effectively avoid hot cracks and stress cracks in the welding process, and simultaneously effectively avoids the defects of incomplete penetration and incomplete fusion by adjusting welding parameters and a welding sequence. |
