Double submerged arc welded straight seam steel pipe is a new welding method invented in 1940, it is the same place and the front of the manual welding it or slag protection, but this residue is not the electrode coating, but melting out welding flux.
Welded vs. seamless steel pipe | American Piping Products
An advantage of ERW pipe is that no fusion metals are used and the weld seam cannot be seen or felt. Thats opposed to double submerged arc welding (DSAW), which leaves behind an obvious weld bead that must then be eliminated depending on the application.
