Soviet Technique for Estimating Post-Welded Deflection: Case of Butt Welding


The hulls of modern ships are almost entirely welded. This makes the prediction of post-welded deformations very important. Some researchers have estimated the post-welded deflections based on empirical and semi-empirical equations. The growing literature on the study of postwelded deflections of hull plates enables the estimation of these deflections based on the plate geometry and the plate material. The limited number of critical parameters covered by these experiments makes it difficult to organize the data systematically. The approach adopted in the U.S.S.R. was to develop an integrated framework to include the critical welding parameters. This paper introduces the Soviet procedure for calculation of deflection due to butt welding, presents the graphical aids used in this procedure, and presents a worked example using this procedure for a butt welded plate.
