Tips for stud welding
Studs, chucks and
ceramic ferrules

In this chapter we have summarized the most important tips
for stud welding. But it does not replace the instruction by the
manufacturer or a trained operator. It only intends to support your
memory.
Studs, chucks and ceramic ferrules must be matched to one
another. For each type of stud DABOTEK offers you the fitting
chucks and ceramic ferrules. You can either order per catalogue
or contact your country representative directly. We would like to
give you advice.
The values for
stud protrusion (see instructions for welding gun)
lift (see instructions for welding gun)
milliseconds (ms)
depend on the diameter and the shape of the stud. The
diameter of the stud is determined in the place which is dipped
into the melting bath when welding, and it can differ from the
nominal diameter. In case of the latter the stud is measured
where it is broadest. This value is often given on the stud itself.
However, you need to know the diameter of the stud in the “dip in
place”.
The values that you take from the welding chart are reference
values. The exact adjustments can only be determined by means
of test weldings in the welding place itself.
According to the type of stud (MD or MR) please, use the
correct welding values.
