关于对大尺寸薄板焊接变形工艺控制的思考与实践

The Thinking and Practice on the Workmanship Control of Welding Deformation of Big Size Thin Plate

本公司在重型燃气轮机进排气系统构件制造中，需进行大量的大尺寸薄板焊接。大尺寸薄板焊接后，经常出现较大的波浪变形，严重影响产品外观质量。根据多年的经验，笔者对大尺寸薄板焊接变形的影响因素进行了全面分析，结合实际提出了对大尺寸薄板焊接变形控制的工艺措施和方法，有效的解决了存在的问题。

There are plenty of large dimension thin plates welding in our company when manufacturing air intake&exhaust system for gas turbine.The welding on big size thin plate often causes wave deformation which seriouslyaffects the products’quality.On the basis of many years’experiences,the author has done a full analysis on thereasons of welding deformation regarding big size thin plate,and offered welding procedures and methods to controlthe deformation of big size thin plate which has solved the existing problems effectively.
