[0031] The working principle is that before use, the welding pipe production line automatic stacking device is arranged at the output position of the welding pipe machine production line, and the welding pipe output by the welding pipe machine production line is located approximately below electric suction device 3.

[0032] In use, the moving assembly 2 is first reset, so that the transverse carrier 21 moves to the position of one end of the transverse direction, and the lifting carrier 22 moves to the highest position.

[0033] When the number of welded pipes output by the welded pipe production line substantially reaches the number of a row (a row arranged perpendicularly to the cross beam 11 is a row) of the stacking, the transverse carrier 21 is transversely moved, the lifting carrier 22 is lowered, the electric suction device 3 is powered after being close to the welded pipes, a row of welded pipes is adsorbed, the lifting carrier 22 is raised, the transverse carrier 21 is transversely moved, so that the row of welded pipes adsorbed by the electric suction device 3 reaches the stacking position, the lifting carrier 22 is lowered, the electric suction device 3 is powered off, and the row of welded pipes is placed on the stacking position or the welded pipes of the previous row, so that automatic stacking can be realized, thereby reducing the labor intensity.
