SOVIET TECHNIQUE FOR ESTIMATING POST-WELDED DEFLECTION: CASE OF BUTT WELDING

摘要: The hulls of modern ships are almost entirely welded. This makes the prediction post-welded deformations important. number parameters involved in process welding is large, so exact mathematical theory for unavailable. Some researchers have estimated deflections based on empirical and semi-empirical equations. growing literature study postwelded hull plates enables estimation these plate geometry material. limited critical covered by experiments it difficult to organize data systematically. has delayed introduction a framework estimating influence deflection from speed, current, passes, rod size material, etc. approach adopted U.S.S.R. was develop an integrated include parameters. From standpoint ship production, useful understand this approach. Therefore, paper introduces Soviet procedure calculation due butt welding, presents graphical aids used procedure, worked example using welded plate.
