2.1 Technology of tip ignition
The SOYER
®
Stud Welding Systems function according to the principle of
capacitor discharge with tip ignition in compliance with DVS leaflet 0903
(German Welding Society).
This system utilises the abrupt discharge of a capacitor battery to generate
electric arc energy.
The electric arc is initiated via the calibrated and close fit ignition tip on the
welding studs and the welding elements. The stud weld base and the opposite
surface of the workpieces is then melted slightly. The stud is automatically
immersed into the thin melted zone and/or the liquid weld bath. After the
immediate solidification of the material, an homogenous high-strength joint in
an extremely short welding time ranging only between 1-3 milliseconds (0.001-
0.003 sec.) is achieved.
