摘要

一种新型的活性钨惰性气体(A- tig)焊接是药界钨惰性气体(FB-TIG)焊接。本研究探讨了2205双相不锈钢(DSS) FB-TIG焊接接头中焊剂间隙的性质和作为单一成分的焊剂在焊缝几何形状上的变化。在2 mm焊剂间隙处，添加SiO2焊剂可显著改善焊深，比TIG焊深提高193%。弧的收缩是造成高穿透深度的主要机制。与此同时，本文还讨论了焊接电流作为热输入对焊缝几何形状、微观结构和机械性能的影响。FB-TIG焊缝的抗拉强度峰值比TIG焊缝金属高10%。然而，FB-TIG焊缝金属的最大显微硬度比TIG焊缝金属低2%。

Flux-bounded TIG welding process in duplex stainless steel: a performance enhancement study

A new variant of activated tungsten inert gas (A-TIG) welding is flux-bounded tungsten inert gas (FB-TIG) welding. The present study explores the nature of flux gap and variation of flux as a single component over the geometry of weld bead in 2205 duplex stainless steel (DSS) FB-TIG weld joint. Significant improvement in penetration depth is observed at the flux gap at 2 mm with SiO2 flux, which is 193% higher than the TIG weld. Constriction of the arc is a predominant mechanism responsible for high penetration depth. Along with this, the article discusses the variation of welding current as a heat input over weld bead geometry, microstructure, and mechanical properties. The peak value of tensile strength of the FB-TIG weld is 10% higher than the TIG weld metal. However, the maximum microhardness of FB-TIG weld metal is 2% less than that of TIG weld metal.
