Weld cracks at storage tanks occur mostly in the process of transverse submerged arc automaticwelding. By linking theory with practice，the authors came to discover some laws why the cracks formed andhow to prevent them, then put forward several measures to control the cracks and some methods for crack in-spection and treatment.2010,2(2): 44-46 收稿日期：2009-2-17分类号：TU972作者简介：刘瑞祥(1962-),男,河北肃宁人,高级工程师,1987年毕业于华北石油职工大学工民建专业,现从事储罐施工技术工作.?
