چکیده
Although solidification cracking is not usually regarded as a serious problem when welding ferritic steels, improvements in the submerged arc welding process, using higher deposition rates and faster welding speeds, have led to welding conditions more likely to give cracking. Furthermore, the need to weld stronger tougher steels, where the inspection requirements are more stringent, has led to a realization that such cracks can frequently be sub-surface and difficult to detect.
