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.
