The smith then heats the metal so that both the iron and steel are molten on the surface. This was evidently quite an art, as the metals had different melting temperatures. The smith closes the seam by hammering it deftly, and the molten metals join. For a two-edged sword, the process is then repeated on the other side.

During the manufacturing process of a can, seam defects may occur and result in. a false seam or an improper seam. Such seams are hazardous in that a good hermetic. seal may not have been formed or the seal may rupture under stress. a. Lipper. A lipper or droop of the end seam is the most common seam defect.
A double seam is a canning process for sealing a tin can by mechanically interlocking the can body and a can end (or lid). Originally, the can end was soldered or welded onto the can body after the can was filled. However, this introduced a variety of issues, such as foreign contaminants (including lead and other harmful heavy metals).
