Özet
In this study, the effect of electrode extension distance on metallurgical and mechanical properties of low carbon steel joints welded with submerged arc welding was investigated. OP 139 flux and OE S1 welding wire were used to weld steel parts using three different electrode extension distances. It is found that electrode extension distance effected the hardness and changed the microstructure of weld metal. It was seen that increasing electrode extension distance reduced the hardness of weld metal and HAZ. Tensile tests showed that rupture occurred in the base metal of all samples. Impact tests revealed that the best toughness value was obtained from the sample welded using 24 mm electrode extension distance.
