Influence of Convexity on the Strength of One-Sided Butt Joints with Incomplete Fusion
摘要
Abstract
SolidWorks Simulation software is used to analyze the stress state of one-sided butt welds that contain a convex element and a gap (incomplete fusion) at the root of the seam. Convexity of the weld seam intensifies the stress concentration due to the gap and increases the maximum stress in the weld. To minimize the stress in the weld, its convexity must be completely eliminated, and a groove of depth equal to the gap height must be made along the whole seam.
