摘要

The invention relates to mechanized Hot Wire GTAW technique for dissimilar weld joints of SS 304H and T91 tube. More particularly the invention relates to an improved HW-GTAW process for dissimilar material tube butt joints of Super 304 H Austenitic Stainless Steel (SS 304H) and 9% Cr and ½ % Mo Ferritic- Martensitic steel (T91). The process can be applied for welding of the boiler components.
