Waterproof welding of tubes on a valve

Welding of a thin-walled tube on a radiator valve.
The machine is in a configured position.
The tube and the valve are being clamped.
The machine starts: the hood is being closed and the welding starts.
The welding movement is of that kind so that the tube is being welded fully waterproof.
At the end of the cycle the hood opens.
Astra-Tec made this solution tailored to the needs of Superia.
