<p>PROBLEM TO BE SOLVED: To improve a work efficiency as well as mounting precision of a reinforcing part by automating positioning of a weld seam in the seam position deciding device to decide a weld seam position of an object on a rotary table. SOLUTION: The seam position deciding device is provided with a seam detection device 10, which outputs low frequency magnetic field from a transmitting coil toward an object 1, receives the reflecting magnetic field from the object 1 with a receiving coil and detects a weld seam based on the received variation of reflecting magnetic field, a table rotating means (6, 12, etc.), which executes scanning of a weld seam for the seam detecting means 10 by rotating a rotary table 5 and a seam position deciding means (10, 12, etc.), which decides a position of the weld seam based on a rotation quantity of the rotary table 5, a position information of the seam detecting device 10, and the seam detection information from the seam detection device 10 and directs the weld seam in a prescribed direction by rotating the rotary table 5 based on a position of the weld seam.</p> |
