6.1 Advice on Stud Welding
The advice on stud welding must be observed prior to commencing to weld. It
contains information important to achieving good welds.
1. Welding elements and workpieces have to be suitable for wel
‐
ding. Only
use material combinations, which are specified in the operating and service
instructions.
2. The welding zone should be even and have a metallic bright finish. Care
must be taken not to exceed a welding zone coarse
‐
ness of 80
μm.
3. Impurities in the welding zone such as rust, forging scales, colo
‐
ring as well
as moisture, fatty matters and oils have to be care
‐
fully removed prior to
commencing welding. Anodised workpiece surfaces must be ground.
4. Workpieces made of aluminum or workpieces with aluminum coating may
only be cleaned with a stainless wire brush or scra
‐
per.
5. Take care that the workpiece is stored free from vibrations (parti
‐
cularly
important in case of large and thin
‐
walled workpieces).
6. Chlorous solvents must by all means be removed from the wel
‐
ding zone.
They may not be exposed to the arc radiation.
7. Poor welding quality as a result of arc blow can be avoided by careful
grounding techniques such as using multiple grounding clamps and
symmetrically positioning the grounding clamps.
8. Ensure that there is good current transfer (low
‐
resistance) in all contact
points in the welding circuit (welding cable connections
– chuck – grounding
clamps).
9. Always lay out the welding and earth cable without any snarls.
Electromagnetic influences can thus be largely avoided.
10.
Check the settings of the N800i welding unit and of the connec
‐
ted gun that
you require for the welding task.
11.
The position of the weld gun and the workpiece may not be alte
‐
red during
the welding process.
12.
Welding on one workpiece with several welding units must be avoided
(electrical danger as a result of higher no
‐
load voltages and possible EMI
