On German Welding
Weld seams are an important, yet often neglected, part of tank production. Obviously, Soviet engineers wasted no time analyzing them on captured German tanks.

"1. Characteristics of weld seams on German tanks.
After looking over numerous types of German tanks, built over a large span of time, it has been established that all German hull and turret armour is welded with electrical arc welding. German armour is only welded by hand.
Automatic welding, used extensively in domestic and American production, is not used by Germans at all.
German welding seams are smooth and aesthetically pleasing."
Automatic welding is significantly faster than manual, requires less physical force, less experienced operators, and is more economical. In the production of the T-34, for example, productivity increased 10 times when using the automatic welding apparatus developed by Dr. Yevgeniy Oskarovich Paton.
