It would be of appreciabale convenience to know prior to undertaking a project of welding a structure the magnitude of the potential angular distortion caused by horizontal fillet welds.This research shows experimental values of angular distortion caused by one pass fillet welding. Material used were all shipbuilding stock of mild steel plating thickness ranging between six and twenty millimetres, and welded under various conditions using leg length between six and ten millimeters. Testpieces totaled three hundred. The magnitude of free angular distortion caused by one pass fillet welding was measured and maximum value of angular distortion was found when flange thickness ranged between ten and twelve millimetres in a tee joint.From the viewpoint of ship welding application, the co-authors, through this reserch, obtained material to predict quantities of free angular distortion caused by one pass fillet welding done with AC arc welders under conditions most applicable to shipyard practice (plate thickness and leg length), and further, material was sought to determine quantities of plastic pre-strain and elastic pre-strain in view of avoiding such distortion. Analytical study on formation of angular distortion was included also.
