Welding process is basic joining technique in shipbuilding. Such method generated welding distortions which cause a lot of problems during the manufacturing process. In the literature it is proposed wide spectrum of suggestions for a correct estimation of welding deformation in particular angular deformation in the fillet welded T joint. In the work influence of oversizing of weld on angular distortions of joint is presented basing upon of the results of the laboratory measurements. Values determined on the basis of literature hypotheses are compared with the one obtained from the laboratory test.
