In general when the objective is to design a low alloy ferritic steel weld metal the first concern from the  beginning is to take into account the factors that influence toughness, especially at low temperatures. At the same time, the possibility to find difficulties to achieve tensile properties is seldom considered. The objective of this work is to analyze the results obtained from mechanical property measurements and microstructural studies in SMAW, FCAW, MCAW and SAW C-Mn-Ni-Mo and C-Mn-Ni-Mo-Cr high strength ferritic deposits from all-weld metal coupons welded according to the relevant AWS standards. The different tensile property requirements of the standards that classify these consumables, used with different welding processes that produce weld metal of similar chemical composition and for similar applications, are also discussed.
