Abstract
A roof panel of a sealed floating roof for a storage tank includes a first frame segment and a second frame segment. Each of the first and second frame segments includes a first depression configured to abut an adjacent top depression of a respective frame segment of a respective adjacent roof panel to form a walled trough to guide an automatic welder along a weld joint during a welding process. The roof panel also includes a panel component. The panel component includes a top sheet and a pan-shaped bottom sheet coupled to the top sheet. The pan-shaped bottom sheet is coupled to a respective upper lip of each of the first and second frame segments.
