The protrusion for PT, UT, IT as well as PS, US, IS type studs should be about
1.5 mm.
Dependent on
– welding process used,
– stud diameter,
– shape of the spatter ring or the welding seam
the protrusion can vary between 0.7 mm and 2 mm.
Gap welding tip ignition
Workpiece
Protrusion of the welding element 1.5 mm
The upper edge of the flange must be flush with the upper edge of the
workpiece.
Contact welding tip ignition
Workpiece
Protrusion of the welding element
Select pin stop one level shorter than standard
e.g. length of the welding element 12 >
pin stop 10
The upper edge of the flange must be 2 mm below the upper edge of
the workpiece.
