Title:
MISALIGNMENT CALCULATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/132561
Kind Code:
A1
Abstract:
A misalignment calculation system provided with a misalignment calculation device for calculating the amount of misalignment when performing a butt weld of the end of a first steel pipe and the end of a second steel pipe, using profile data measured in the circumferential direction given a preset first angle reference for the end of the first steel pipe, and profile data measured in the circumferential direction given a preset second angle reference for the end of the second steel pipe. The misalignment calculation device is capable of numerically evaluating misalignment when performing a butt weld by using the angle formed by the first angle reference and the second angle reference as an input angle, and calculating the amount of misalignment in a state where the center of the profile data showing the outer contour of the end of the first steel pipe and the center of the profile data showing the outer contour of the end of the second steel pipe are the same.
