Abstract
High speed and high performance submerged arc welding (SAW) with multiple electrodes is used for the corner joint welding of box column for the structural steel fabricated in Shimizu Works. The authors have developed a system to control the penetration depth of the welding and its associated system, and have adopted them into commercial projects. It was confirmed that satisfactory and stable performance of welds, which was used to be highly dependent on the skill of experienced operators, have been achieved by the system.
