ADJUSTMENT METHOD FOR WORKPIECE POSTURE, AND METHOD OF AND DEVICE FOR PRODUCING MOLDED MATERIAL

摘要

To provide an adjustment method for workpiece posture capable of adjusting at high accuracy, the posture of a circular cross section-shaped workpiece while saving a cost of equipment, and also to provide a method and device capable of producing a high-quality molded material by laminating weld beads to the workpiece.SOLUTION: A posture adjustment method for a workpiece 20 includes: a position detection process of detecting a position of the workpiece by contacting a filler metal M protruding from a torch 17 on the peripheral surface of the workpiece 20 in plural circumferential positions R1, R2, R3 in plural axial positions Z1, Z2 being plural places in an axial direction of the workpiece 20; a coordinate calculation process of calculating the coordinate of a detected position; an inclination calculating process of calculating inclination of the workpiece 20 from the coordinate of the detected position; and a posture adjustment process of adjusting the posture of the workpiece 20 to a previously set one by a support mechanism 16 on the basis of the calculated inclination of the workpiece 20.SELECTED DRAWING: Figure 1
