Glossary
Automatic welding head:
Device for welding of welding elements
Capacitor:
Component for storage of electrical energy.
Light arc:
Independent gas discharge between two
electrodes when the current is high enough.
A whitish light is emitted in the process. The light
arc allows very high temperatures to be generated.
Rectifier:
Electrical component that converts alternating
voltage into direct voltage
Stud feeder:
Device for automatic feeding of welding elements
Stud welding gun:
Device for welding of welding elements
Stud welding machine:
Stud welding unit including stud welding gun
Stud welding unit:
Device for provision of the electrical energy for
stud welding
Thyristor:
Electronic component for contact-free switching of
high currents; switching takes place via the control
input
Welding element:
Component such as stud or pin that is welded to
the workpiece
Welding parameters:
Mechanical and electrical settings at the stud
welding gun and at the stud welding unit
(e.g. spring force, charging voltage)
Workpiece:
Components such as sheet metal or tubes to
which the welding elements are to be fastened
