[0002] Due to the welding characteristics of submerged arc welding, stable welding quality can only be ensured in the flat welding position. When welding the longitudinal seam of a conical body, the inner side weld of the conical body longitudinal seam can be placed on a platform for submerged arc welding. However, the outer side of the conical body longitudinal seam is on a slope surface, and conventional submerged arc welding cannot be carried out. Although there are also studies on submerged arc horizontal welding and vertical welding in the current industry, the weld quality is not ideal from the current situation. Content of the Utility Model

[0003] To solve the defects of the above-mentioned existing technologies, the utility model provides a submerged arc welding tooling for the longitudinal seam of a conical body, aiming to enable submerged arc welding to be used on the outer side of the conical body longitudinal seam. The tooling is convenient to use and applicable to conical bodies with various diameters and any thicknesses. Laying the conical body weld flat can improve production efficiency while ensuring weld quality.

[0004] To achieve the above technical purpose, the utility model adopts the following technical scheme: A submerged arc welding tooling for the longitudinal seam of a conical body includes a base. Four load-bearing support pipes, two supporting H-shaped steels, four inclined support pipes, and a sling are fixed on the base. Two of the load-bearing support pipes are vertical and parallel to each other and fixed on the base. The other two load-bearing support pipes are inclined and parallel to each other and fixed on the base. The bottoms of the two inclined load-bearing support pipes are respectively fixed to the bottoms of the two vertical load-bearing support pipes. One end of two of the inclined support pipes is fixed to the two vertical load-bearing support pipes, and the other end is fixed to the base. One end of the other two inclined support pipes is fixed to the two inclined load-bearing support pipes, and the other end is fixed to the base. The sling is fixed on the supporting H-shaped steel and used to pass through the conical body to lift the lower end of the conical body. It also includes a G-type clamp, and the G-type clamp fixes the conical body on the supporting H-shaped steel.

[0005] Further, the base includes six H-shaped steels. Four of the H-shaped steels enclose a rectangle for fixing the four inclined support pipes, and the other two H-shaped steels are fixed in the middle of the rectangle for fixing the four load-bearing support pipes.

[0006] Further, it also includes four limiting pipes, and the four limiting pipes are connected between two adjacent load-bearing support pipes one by one.

[0007] In summary, the utility model has achieved the following technical effects:

[0008] The utility model lifts the height of the vertebral body, stands the vertebral body up, and then uses a sling to change the center of gravity of the vertebral body, so that the outside of the longitudinal seam of the vertebral body reaches the horizontal position, thereby achieving the purpose of using submerged arc welding for the longitudinal seam of the vertebral body, improving the welding efficiency and the weld quality.
