English: Automatic butt-welding machine
Butt welding is a welding technique used to connect parts which are nearly parallel and don't overlap. Butt-welding is an economical and reliable way of joining without using additional components. Butt-welding joint is made by gradually heating up the two weld ends with a weld plate and then joining them under a specific pressure.
This machine was built 1926 in Köln, Germany.
