1 Cleaning welding area and drill at an incline into the end of the crack.
The angle should be greater than 15° and the drill diameter greater than 6 mm.

4 Weld shut the V-seam in several positions (4, 5 and 6).
Do not weld the bore completely shut. When welding, swing the top layer (6) with the electrode to the left and right and back again, and stop for a moment (approx. 2 s.) at the right and left with the electrode, to ensure that the electrode has a sufficient drip period and thereby prevent any undercuts. Always weld from above downwards. After welding, particular care should be taken to ensure that slow and uniform cooling is given.
