Abstract
PURPOSE: To obtain the captioned plated steel pipe free from any welding defect occuring in the remaining of aluminum oxides at the welding by removing the plating layers near the butt portions of an Al or Al alloy plated steel hoop between the slitting process of said steel hoop and its roll forming process.
CONSTITUTION: Blank steel 1 comprising slitting an Al or Al alloy plated steel hoop to the specified width has the abovementioned plating layers 2 on both surfaces. At the time of producing the steel pipe by roll forming this blank steel 1, a process for removing the plating layers near the butt portions 6, 7 of the blank steel 1 is provided and the shear droops 4, 5 of the plating layers are removed by shaping them off with, e.g., a grinder or the like. As a result, the inclusion of oxide aluminum into the deposited portion at the butt welding does not occur and the Al plated or Al alloy plated steel pipe free from any welding defect such as crack, etc. occuring in the remaining of aluminum oxides is obtainable.
