Welding method and welding device for outer ring weld joints of steel pipe piles

Abstract

The invention relates to a welding method and a welding device for the outer ring weld joints of steel pipe piles. The welding method comprises the following steps: the butted steel pipe piles are placed on a rotary support device, a movable operating platform is adopted, and welding equipment is arranged on the movable operating platform and conducts outer ring weld joint welding operations above or beside the butt joints of the steel pipe piles. The welding method and the welding device for the outer ring weld joints of the steel pipe piles are reasonable in design and flexible to operate, and are adapted to simple and fast up-and-down adjustment of steel pipe piles of different diameters; and the welding equipment moves fast, is simple and convenient to operate, has stable properties, relieves the labor intensity of operators, improves the working efficiency and the welding quality, fully utilizes the height of the space in a workshop, and saves the ground construction field.

Description

technical field [0001] The invention belongs to the welding technology of steel pipes for steel pipe pile construction, and in particular relates to a welding method and a welding device for the outer ring welds of steel pipe piles with different large diameters Background technique [0002] With the rapid development of port construction and the designed berthing tonnage of the wharf is increasing. The diameter of the steel piles produced now is also increasing and the specifications are various. Steel pipe piles are foundational tools for cofferdams used to realize infrastructure construction such as bridge piers and foundation components for infrastructure construction such as wharf caps. The diameter of the steel pipe piles can reach several meters, and multiple strip steel plates are required for longitudinal welding A multi-section steel pipe pile is formed, and then the inner and outer ring welds of the multi-section steel pipe pile are welded to finally reach the de...

AI Technical Summary

Problems solved by technology

[0003] When the multi-section butt welding of the steel pipe pile is carried out, the existing manual operation method cannot guarantee the stability of the welding operation of the outer ring weld, and the labor intensity of the operator is relatively high

For the welding of steel pipe piles with different diameters, various auxiliary equipment adjustments are required, which leads to low welding quality and welding efficiency
