摘要 钨极氩弧焊(GTAW)具有操作方便,焊接质量好等优点,在关键的焊接生产中应用较多,特别是在压力管道以及锅炉压力容器的打底焊中被普遍采用。在氩弧焊焊接过程中,焊工采用不同的焊接手法对焊接质量有较大的影响。以小口径管道氩弧焊为例,分析了三种施焊手法对焊道外观成型及焊接质量的影响,总结出管道现场焊接中合适的焊接手法,以提高压力管道现场焊接的一次合格率。 Gas Tungsten Arc Weld( GTAW),which was characterized as flexible operation,high welding quality,is widely used in critical welding production,especially in the backing welding of pressure pipelines,boilers and pressure Vessels. In the process of GTAW,the use of different welding methods has large influence on the welding quality. In this paper,we take the GTAW of small-diameter pipeline as an example to analyze the effect of three welding methods on the appearance forming of weld pass and the welding quality,and to summarize an appropriate method during the site-welding of pipelines. Therefore,the pass rate of site-welding of pressure pipelines was increased.
