Effect of Misalignment of Axes in Double-Sided Weld on Stresses Distribution in Butt Welded Joints

Abstract

An analytical method for calculation of local stresses in double-sided butt welded joints at misalignment of welds’ axes is developed. The method is applicable for welded thin-gauge plates with different geometry of welds on the face and root sides under tensile load. In the given calculation example, it was shown that the stresses reach their maximum value in the zone of transition from the root weld to the base metal which is farther from the axis of the face weld. The results of analytical calculations are in good agreement with the results obtained using the finite element method.
