Özet

In this work, low carbon steel and hardox steel joined by using submerged arc welding under three different conditions. Same welding parameters (325 A, 30-32 V) were used during welding. Welded joints were characterised in terms of hardness test, macro and microstructures. The results indicated that hardox welded joints showed the highest hardness. In addition, as a result of macro and microstructure study, heat affected zone (HAZ) of structural steels were observed much larger.
