After the transverse ribs on the two sides are placed, one welding mechanism 1 on one side is controlled to move to the welding mould 2 in the middle position, and the transverse ribs are placed at the position. It should be noted that, the transverse ribs on each welding mold 2 can be placed in a plurality of positions according to the positioning net 10 structures of different specifications.

After the transverse bar is placed, the longitudinal bars are placed and welding is performed synchronously, specifically, the welding mechanism 1 at each position is moved to the first position for placing the longitudinal bars, then the steel bars are fed to the positions of the transverse bars through the feeding device 11, at the moment, the third driving piece 133 is driven by the first driving piece, the upper electrode 131 is driven to move above the crossing position of the transverse bars and the steel bars, the lower electrode 132 is driven by the second driving piece to move below the crossing position of the transverse bars and the steel bars, the lower electrode 132 is driven by the third driving piece 133 to be pressed to the crossing position of the transverse bars and the steel bars, the steel bars are sheared into the longitudinal bars through the shearing device 12, and then the crossing position is welded through the cooperation of the upper electrode 131 and the lower electrode 132.
