The vertical feed fly saw, equiped on most straightwelding pipe sets, can not be suitable to cut square shaped pipes because of serious deformation on the cut face.
At the same time, analyze the welding deformation of straight-line segment model of side rail, and compare the results with test data, verify this method is efficient.
