船舶气电立焊工艺与参数控制

Controlling of technology and parameter in electro-gas welding in shipbuilding

随着我国船舶制造领域步伐的加快,大型分段焊接合拢工程也随之增加,厚板垂直焊缝采用EGW技术代替传统的人工焊接,在质量提高的同时,生产效率提高了十几倍。以图解形式介绍EGW工作原理、设备构造,阐述了在EGW焊接中衬垫形式、工艺参数、焊丝对接头质量的影响及控制。

With shipbuilding field rapidly developing in our country,more and more large-scale locking engineering are expanded.Many shipyards use EGW technology instead of manual welding to weld vertical seam in thick plates.This method is not only improved the quality ,but also raised dozens times efficiencies.The paper introduces operation principle ,equipment structure of EGW in illustrated diagram.The paper expounds weld quality how influenced by the backing strap forms,technology parameters,weld wires and how to control.
