概要:
船殻ブロック同士の突き合わせ溶接を上向き姿勢ワンラン施工にて完了することのできる新溶接法を開発した。この新溶接プロセスにおけるビード形成モデルの構築とその数値解析を通し，実適用での安定施工と溶接部の健全化を達成した。
Abstract:
Quite new automatic arc
welding process and equipment have been developed that can
weld ship's shell plates, upwards from the ground. The welding
equipment can complete a butt joint of ship's shell plates
with one running process. In order to keep the welding process
under control, it is important to know formation mechanism
of the weld bead in this process. A control system based
on a weld bead formation model has achieved a smooth running
process and a quality weld deposit.
