Seamwelding

Seamwelding is the act of welding two similar metals together at a seam, usually on a piece of automated equipment. This process differs from buttwelding, as that is generally a process that is done on static (non-moving) metals.

Seamwelding consists of two (or more) moving metals through forming production equipment. A common use of seamwelding is for copper and steel piping for construction. Varying the amperage as well as speeds of the moving metals ensure a proper seamweld, and many industries use this process for creation of finished goods.
