Systematic studies of the relationship between welding procedure and all-weld metal properties of low alloy ferritic steel metal cored wires have so far not been undertaken. The study of solidification and solid phase transformations is necessary to explain and to be able to predict the mechanical properties of the deposits. The objective of this work was to study the microstructural and mechanical characteristics of 0.05% C-1.7% Mn-0.45% Si- 0.95% Ni all-weld metal from an ANSI/AWS A5.29-98 E81T5-G type metal cored wire when the welding procedure parameters were changed. On the other hand, solidification and solid phase transformations were analyzed to obtain metallurgical information on this system.
