【Abstract】 In the article, the numerical simulation software ANSYS is used to analyze the working stress distribution in butt joint and the effect of the geometric parameter on the stress concentration efficiency. It provides a theoretical proof for the choice of the welding joint sectional shape and dimension, and for increasing the length of life and stability of the weld structure, and for design and manufacture in the weld structure.更多还原
