Close the support.
Check pipe mismatch and gap on the joining pipe ends
(gap max. 0.5 mm). The mismatch between the pipe
ends should be 1 – 2 mm (see the sketch).
It is reached by moving the left-hand T-piece clamping
device in the longhole of the fixing screw
(after welding the mismatch is compensated again).
The welding process is the same as for straight pipes. Multiplicate the force values taken from
the table with factor 1,41.
After expiration of the cooling time, release the force, remove the welded parts and open the
support.
