Square pipes welding
From welding square tube deformation theory shows that the impact of welding deformation square tube size is a major factor: the larger the size of weld, weld more metal, the greater the deformation; weld sizes are equal, the greater the weld heat input, resulting in deformation greater; welded square tube big long weld time, welding deformation segment is smaller than the straight; welds arranged asymmetric or symmetric, but asymmetric arrangement, although welded pipe, welds more serious deviation, the greater the deformation; The smaller component rigidity, the greater the deformation.
