超大型焊接卷筒的强度校核及焊接工艺研究
Strength Verification and Welding Process Research of Ultra Large Welding Drum
摘要
Abstract
This article is based on the elastic-plastic theory and introduces the stress state of ultra large welding drums under different loads.The strength verification formula of ultra large welding drums is obtained,providing theoretical guidance for the design of drum wall thickness.In addition,research was conducted on the welding process of the cylinder body and the outer flange plate assembly of the ultra large welding drum.The research showed that the cylinder welding joint obtained by alternating welding of the inner and outer grooves in a ratio of 1/4 has excellent comprehensive mechanical properties.The use of short weld seam segmented welding ensures the assembly welding strength and verticality requirements of the outer flange plate of the drum by correcting the alternating welding sequence on both sides.关键词
