The horizontal joint is aligned while the tank is continuously rotated. This means that the tack welding is very simple, fast and extremely cost effective. When attaching any required stiffening rings, the stand is also used to fix each individual ring segment to the shell plate.

The stand is equipped with a track which enables a totally autonomous mechanized welding process of both the vertical and horizontal weld seams. It is also possible to use this device to fillet weld required stiffening rings to the outer shell. It can be used with all common industrial welding methods designated by the customer.
