Development of a Composite Consumable Insert for Submerged ARC Welding.

摘要

The composite development program was initiated by Mr. William S. Srayton, at the time Chairman of the Shipbuilding Committee of the Maritime Administration. The problem was related to the welding of heavy thickness plate that requires welding from both sides. When the submerged arc process was utilized to weld the butt joint in large flat plate structures, the repositioning of the plate for welding of the reverse side was a costly time consuming procedure. The objective was to develop a joint design and modified submerged arc welding process that would enable full penetration welding from one side. The modified process would eliminate the need for repositioning of the plate.
