| Abstract: | In this study, different welding parameters were applied to two different steels with high alloys and mechanical and metallographical
investigations are performed. Thus, the optimum welding parameters were determined for these materials and working conditions.
12·30 diameter steel bars made up of 1·4871 (X53CrMnNiN219) and 1·4718 (X45CrSi93) steel were used as experimental material.
The material loss increased with increase in friction and rotating pressure. No fracture at the welding region was observed
and the highest fracture energy was identified in B5 group. Based on micro hardness investigation; the hardness profile reached
its minimum value at the welding region. |
