Abstract

This paper deals mainly with two types of new materials namely SA213T23, SA213T92 with specialemphasis 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 argongass hielding. Two combinations of dissimilar welds were carried out and testing was also done. Testing methods comprises of radiography test, transverse tensile, facebend, rootbend, impact, macro,microand 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.
