WebModules include materials science, technology and an understanding of the characteristics and weldability of different materials, ranging from steels to non-ferrous materials. Also, cracking phenomena are presented together with methods to avoid them. We have introduced a new suite of eLearning options for the TWI Diploma. WebFriction stir welding (FSW) is an innovative solid-state process, patented in 1991 by The Welding Institute, which avoids solidification problems associated with conventional fusion welding, providing joints having excellent mechanical and metallurgical properties. Due to its many advantages, FSW is successfully applied to weld various ... WebTWI Carbon Equivalent The CE of steel primarily relates to its hardenability. Higher the CE, lower the weldability Higher the CE, higher the susceptibility to brittleness The CE of a given material depends on its alloying elements The CE is calculated using the following formula CE = C + Mn + Cr + Mo + V + Cu + Ni 6 515 CE = C + Mn 6 M.S.Rogers bopp poly bag
