<p><P>PROBLEM TO BE SOLVED: To provide a method for welding a stub to an electrode with high precision at the outside of a mold. <P>SOLUTION: The distance between the outer circumference of an electrode 1 and a distance measuring sensor is measured by the distance measuring sensor. Based on the measurement information, the cross-section of the electrode and a virtual mold circle B are drawn, and points G<SB>P1</SB>', G<SB>P2</SB>' and G<SB>P3</SB>' in the electrode at which the variation of virtual side gaps Ln, L'n between the outer circumference of the cross-section in the electrode and the virtual mold circle is made the minimum are calculated. Based on the central point, calculation is performed in such a manner that the inclinationθof a virtual axis Z to the passing core of a mold/stub clamp reaches≤1.5 mm/m. Further, calculation is performed in such a manner that the central point of the virtual axis Z vertically moves along the passing core to the upper end face 1a of the electrode, thus its intersection G<SB>P</SB>'' with the upper end face of the electrode is obtained, and a stub is arranged at the intersection, so as to be welded. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
