Description

Technical Field

[0001] The utility model belongs to the field of heavy steel pipe welding, in particular to a welding platform for the outer weld of a heavy steel pipe. Background Art

[0002] Heavy-duty steel pipes are hollow-section steel products whose length is much greater than their diameter or circumference. They are categorized by cross-sectional shape into round, square, rectangular, and special-shaped steel pipes; by material, they are classified into carbon structural steel, low-alloy structural steel, alloy steel, and composite steel pipes; by application, they are used for pipelines, engineering structures, thermal equipment, the petrochemical industry, machinery manufacturing, geological drilling, and high-pressure equipment. By production process, they are categorized into seamless and welded steel pipes. Seamless steel pipes are further divided into hot-rolled and cold-rolled (drawn) types, while welded steel pipes are further divided into straight-seam welded and spiral-seam welded types. Steel pipes are not only used for conveying fluids and powdered solids, exchanging heat, and manufacturing mechanical parts and containers, but are also an economical steel material. Using steel pipes to manufacture structural grids, pillars, and mechanical supports can reduce weight, saving 20-40% of metal, and enable factory-based, mechanized construction. Using steel pipes to construct highway bridges not only saves steel and simplifies construction, but also significantly reduces the area covered by protective coatings, saving investment and maintenance costs.
