Claim 0:
1. A method comprising:
scanning a geometry and a cross section of a weld joint;
estimating, based on the scanning, a total number of runs to weld the weld joint using a submerged arc welding (SAW) operation;
monitoring the SAW operation in real-time;
determining, based on the monitoring and the scanning and the estimating, a discrepancy between a desired weld parameter and an actual weld parameter of a weld resulting from the SAW operation; and
in response to determining the discrepancy, controlling a power supply, which provides power for the SAW operation, to modify at least one of balance or offset of an alternating current (AC) welding power signal supplied for the SAW operation to compensate for the discrepancy.
