This paper deals mainly with two types of new materials namely SA213 T23, SA213 T92 with special emphasis on dissimilar combinations due to its advantages in production welding of super heater tubes mainly in tube to tube joints and tube to header joints. Welding was carried out under manual TIG process with argon gas shielding. Two combinations of dissimilar welds were carried out and testing was also done. Testing methods comprises of radiography test, transverse tensile, face bend, root bend, impact, macro, micro and scanning electron microscope tests. The results from these tests prove that the dissimilar joints made with the newer steel grades holds good for super heater components of power boilers with better properties.
