The large rectangular vacuum container processing technology according to claim 1, characterized in that: The following steps are involved: S1: The original sheet is stretched, the original sheet is placed on the mold of the stretching device, the original sheet is stretched and formed multiple times by the stamping parts, and the outer shell or liner is made after metal processing; S2: Welding joint positioning: the staff puts the outer shell and the inner liner of the container together, and spot welds the four center points and the starting and ending points of the chamfers on the welding joint between the outer shell and the inner liner, and then uses a laser positioning device to color-mark the welding joint between the outer shell and the inner liner; S3: The container is fixed, and the fixed structure is controlled to move so as to match the inner liner of the container, thereby fixing the container on the rotating structure; S4: Following positioning, driving the following wheel to contact the starting point of the weld at the bottom of the container through the lateral moving structure; S5: Color mark positioning, the lifting structure drives the welding gun to descend, and starts the hydraulic cylinder, the hydraulic cylinder drives the welding gun to move, the color mark sensor of the welding gun auxiliary police is activated by the label at the starting point of the weld, and the welding point on the welding gun contacts the weld; S6: straight-mouth welding, start the welding gun, and through the cooperation between the color code sensor and the follower wheel, enable the welding gun to weld the welds on the four sides of the container; S7: arc weld joint welding, after the color mark sensor recognizes different color marks at the arc weld joint, the angle of the welding gun and the speed of the turntable are adjusted to weld the arc weld joint of the container; S8: The container is evacuated. The staff evacuates the container through a vacuum pump and seals the air extraction port on the container; S9: Weld polishing and leak detection: the staff manually polishes and leak detects the weld of the container; S10: Container polishing, polishing the inner and outer surfaces of the container; S11: Container spraying: spraying anti-rust paint on the outer surface of the container.
