A reduction in the consumption of energy for correction of welding distortion is demanded from the environmental and economical point of view. So, a welding consumable (welding wire), for which it is unnecessary to correct the welding distortion, was newly developed. Based on the mechanical properties of welds using an existing welding wire, the mechanical properties of welds using the newly developed welding wire were evaluated. Moreover, the structural soundness of welds was evaluated from the characteristics of structures produced by each welding wire. Despite the fact that the mechanical characteristics of the newly developed welding wire were a little inferior to an existing welding wire, it does not present much of a problem to practical use from the overall point of view |
