10. A pressure vessel processing weld assembly for aerospace testing according to any one of claims 1-9, wherein: the welding method specifically comprises the following steps:
the method comprises the following steps: the container is moved between the two brackets (3) by a forklift, then the brackets (3) are pushed towards the middle and moved to the bottom of the container, then the brackets (3) and the positioning plates (39) are fixed together by high-strength bolts (9), then the forklift is controlled to carefully place the container on the brackets (3), and then the forklift is removed;
step two: after the container is placed, firstly pulling the folding platform (34) and the supporting plate (35) apart, supporting the joint of the inclined supporting rod (33) and the underframe (1) by the supporting plate (35), enabling a worker to stand on the folding platform (34), holding the handle (28) for welding operation, if circumferential welding is needed, pushing the container by the other hand to enable the container to be in rotating fit with the welding, if welding is needed to move left and right, firstly pulling the handle (28) towards the upper right to enable the upper sliding sleeve (20) and the lower sliding sleeve (21) to be opened, and then moving the welding gun (2) left and right, if the welding gun is needed to be fixed at a certain position, only loosening the pulling force, and pulling the upper sliding sleeve (20) downwards by utilizing the restoring force of the spring (25), so that the friction plate (26) can be tightly pressed on the tops of the U-shaped main;
step three: if the welding angle, the welding distance and the like of the welding gun (2) need to be adjusted, the handle (28) can be pulled towards the left upper side, so that the short round shaft at the joint of the first connecting rod (15) and the second connecting rod (16) is separated from the first buckle (12), the clamping ring (19) is separated from the second buckle (18), the first connecting rod (15), the second connecting rod (16) and the third connecting rod (17) can be unfolded, and the angle position of the welding gun (2) can be adjusted freely.
