During submerged arc welding (SAW), filler materials (wire and flux) play a leading role on the weld joint quality. Nowadays, the variety available filler materials which are available in welding technology, does not make it easy to select them, but on the contrary makes it very difficult. The wide range of wire and flux combination in the steel pipe industry can make selecting the best weld joint quality, although often it is not a simple issue since there are several factors to be considered. When the selection is performed correctly, welded joint mechanical and technological properties are at least equal to that of base metal, higher to that of base metal or in worse case, lower to that of base metal. Among the mechanical properties of the welded joint, tensile strength (Rm) of the welded joint is the most important feature that helps in the selection of the filler materials (wire and flux) for submerged arc welding (SAW) of steel pipes, while in the framework of technological properties, plasticity of the welded joint is the most important feature that helps in the selection of the filler materials (wire and flux).This paper presents the selection of filler materials (wire and flux) for submerged arc welding (SAW) of welded steel pipes from the aspect of the tensile strength (Rm) and plasticity.
