[0033] The processing personnel obtain H-shaped steel and two T-shaped steels of matching specifications. The processing personnel vertically place the web of the H-shaped steel in the middle of the bearing groove 14 outside the limiting strip 15 on the inner side of the bearing groove 14. The limiting strip 15 is in contact with the lower flange plate of the H-shaped steel and limits the sliding of the lower flange plate.

When the welding of the web of the H-shaped steel and the web of the right T-shaped steel is completed, the table plate 11 is controlled to rotate clockwise by 90°, so that the welding position of the web of the H-shaped steel and the web of the left T-shaped steel is vertically upward for welding.
