This paper conducts a comparative study on two types of skirt welding:conventional skirts and skirts with steps.Utilizing the finite element analysis software ANSYS WORKBENCH,the impact of the welding type between the skirt and the head on the stress of the skirt is analyzed.The results show that compared with conventional skirts,the welding type of skirt with steps can effectively improve the stress level at the weld seam between the skirt and the equipment head.Additionally,it is further ex-amined the influence of environmental temperature values on the stress of skirts with different welding types.The analysis results offer valuable insights for calculating skirt stress and provide recommendations for se-lecting the appropriate welding type between skirts and heads.
