Some common design choices for sheet metal joints are based on usage and seam characteristics. The resulting shape may even form a seal that isolates one side of the sheets from the other. Web a seam is used to connect two metal parts by interlocking the edges of the folded sheet metal parts. Web hemming and seaming are two similar metalworking processes in which a sheet metal edge is rolled over onto itself. Web seams run parallel to the air flow, while joints are perpendicular to the air flow. Web from the outside, you may only see a seam, bump, or nothing at all. Hemming is the process in which the edge is rolled flush to itself, while a seam joins. The seams hold together the duct or section of a single fitting as opposed to a joint that connects two separate pieces.
