LOOSE PIECE INSTALLATION METHOD FOR WELDED STRUCTURE

摘要

The present invention relates to a construction method of a loose piece for interference avoidance between circular members (10) in a process for assembling a welded structure comprises: a step (a) for determining the position and shape of a cutting member (20) on a circular member (10); a step (b) for forming a cutting hole part (30) along the determined contour line of the cutting member (20); and a step (c) for filling the cutting hole part (30) after application termination and restitution of the cutting member (20). Therefore, the present invention has an effect of improving productivity and quality by exclusion of a loose piece by using a cutting line shape for automatic cutting and automatic improvement constructing in a field of manufacturing various structures required for a ship or the like.
