C編}, month = {Aug}, note = {Iron-frame box-columns are made by continuously welding steel plates. The inclination of the box-column must be kept constant under the deformation due to the thermal disturbance to maintain stable electric discharges. This is generally done by manipulating one of two oil hydraulic tandems which support the box-column. In this study, an automatic control method is proposed. An advantage of this control method is that it solves the problem of the detected variable differing from the controlled variable. All box-columns made using this automatic control method show satisfactory results both in external inspection and under ultrasonic inspection.}, pages = {2739--2746}, title = {鉄骨BOX柱の角溶接時における傾度制御}, volume = {63}, year = {1997} }
