SOLIDIFICATION CRACKING OF FERRITIC STEELS DURING SUBMERGED-ARC WELDING

This report is concerned with a programme sponsored in 1971 by 15 companies together with Det norske Veritas and ESAB to investigate solidification cracking during submerged-arc welding which, at that time, showed signs of becoming an increasingly severe problem. Although weld solidification cracking (hot cracking) is not a new problem, it was not encountered to any serious extent in welding structural and pressure-vessel steels until the advent of submerged-arc welding. This process, with its characteristically large weld pools and capacity for high energy inputs, is particularly prone to solidification cracking, which may vary in intensity from isolated small defects to the cracking of entire weld seams. The results of the investigation are summarised together with other knowledge in this field, in such a way as to be of help to fabricators and others who may be concerned with welding C-Mn steel and, in a more general way, low-alloy steels. The subject is covered under the following headings: Description of solidification cracking. Detection, significance, and identification. Avoidance of solidificaton cracking. Remedial measures when cracking is encountered during fabrication. Order from: BSRA as No. 47,325.
