Remaining under the cool-down time for up to 50% is allowed under the following conditions:
•
prefabrication under workshop conditions
•
low additional pressure at unclamping
•
no additional pressure during further cooling down
•
load onto the workpieces only after being completely cooled down
•
Join parts with wall thickness ≥15 mm
