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 welding. 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 coarseness of 80µm.
3. Impurities in the welding zone such as rust, forging scales, coloring as well as
moisture, fatty matters and oils have to be carefully 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 scraper.
5. Take care that the workpiece is stored free from vibrations (particularly important
in case of large and thinwalled workpieces).
6. Chlorous solvents must by all means be removed from the welding 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 N1500i welding unit and of the connected gun that you
require for the welding task.
11. The position of the weld gun and the workpiece may not be altered 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 interference).
