双钨极氩弧焊工艺及焊缝成形机理分析

Twin-electrode TIG welding procedure and mechanism of weld formation

    摘要
  • 摘要: 针对3 mm和4 mm厚度低碳钢板,对双钨极氩弧焊的焊接工艺进行了研究。与常规钨极氩弧焊的对比分析表明,由于双钨极氩弧焊降低了电弧压力,提高了焊丝的熔敷率,因而在大电流高速度焊接时,极大地减少了凹坑、咬边等缺陷,实现了良好的焊缝成形,从而改善了常规钨极氩弧焊不适合大电流高速度焊接的不足,拓宽了钨极氩弧焊的使用范围,提高了焊接生产率。此外,在焊接试验的基础上,进一步对双钨极氩弧焊降低电弧压力、减少焊接缺陷的机理进行了分析。

     

    Abstract: The twin-electrode tungsten inert-gas(T-TIG) welding was studied by using the base metal of Q235 low carbon steel plate with the thickness of 3 mm and 4 mm.The results indicate that the T-TIG welding can avoid the defects of undercut and humping effectively in high current and high speed region on the basis of low arc pressure.Accordingly the deposition rate is increased, and the weld formation is improved.In addition, the mechanism of the T-TIG arc pressure reduction to make the sound weld formation was analyzed.
