X-Ray Radiography of Micro-alloyed Steel Joined by Submerged Arc Welding

Abstract

In this study, micro-alloyed steels were welded by using submerged arc welding method. Different welding current values ??in experimental studies were carried out according to Table 3. After welding process, the radiographic tests were examined by using X-Ray. The experimental results indicated that microalloyed steel could be joined by using the submerged arc welding technique with sufficient strength. The results of the radiographic tests indicated that with increasing welding current, the amount of deep penetration increased in all samples.
