17. Check weld root on the underside of the sheet, determine
Z position for focus position of f=0.
The focus position of f=0 is reached when the welding root on
the bottom of the sheet can be clearly seen with full
penetration welding. This is the case with position Z0+7 in the
reference part illustrated below.

18. Determining deviation from nominal dimension:
Z0 Z0+1 Z0+2 Z0+3 Z0+4 Z0+5 Z0+6 Z0+7 Z0+8 Z0+9 Z0+10
-5 mm -4 mm -3 mm -2 mm -1 mm 0 mm +1 mm +2 mm +3 mm +4 mm +5 mm
Shorten welding nozzle un-
changed Lengthen welding nozzle
Deviation from nominal dimension valid for
Z0 = 10 mm nozzle distance
Note
The position Z0 corresponds to a nozzle distance of 10 mm.
The Deviation from nominal dimension is the amount by which
the length of the welding nozzle needs to be corrected; a
corrected nominal dimension is set at the welding head.
In the illustrated reference part, the focus point lies at Z0+7,
corresponding to a nozzle distance of 17 mm; welding is done
with a 15 mm nozzle distance. The Deviation from nominal
dimension amounts accordingly to +2 mm, which is the amount
by which the length of the welding nozzle needs to be
corrected. The nozzle needs to be made 2 mm longer in such
cases.
