Abstract
Solid-state welding provides a distinct state of the art to joining various metal tubes. In contrast to other types of welding, dissimilar joining by solid-state welding maintains the integrity of its joints. Dissimilar joints of UNS S31803 and UNS S30400 tubes were carried out using rotary friction welding process. Three combinations of tube joints fabricated were, ASS to ASS, DSS to DSS and ASS to DSS joint. The tensile tests showed dissimilar weld joint achieved the minimum strength of ASS similar joint. Fractography for similar and dissimilar tube joints showed a ductile pattern of fracture with dimples and voids in the dissimilar tube weld. Microstructure analysis showed that diffusion bond line for similar and dissimilar joints confirms the sound weld tube joints. Corrosion test showed that among three combinations, ASS to DSS dissimilar joint had lesser corrosion rate than ASS to ASS or DSS to DSS similar joints.
