(History
/ Definition / Principle of Stored Energy Welders /
Welding)
|
History:
Stored energy welders were developed between 1985 and
1990. A design patent was registered in 1995 by Rick
D. Wilson in USA.
Definition: The enhanced process of resistance welding
by supply energy to work in 2 to 5 milli seconds instead
of 100 ms + from a energy stored source.
Principle: The stored energy welding machine extracts
energy from the power line over a period of time and
stores it in a high voltage capacitor's bank. The stored
energy is discharged through a pulse transformer which
converts the high voltage pulse into the required high
current pulse (at low voltage) which is delivered by
highly conductive cables to the welding head and passes
through the work piece.

Stored
energy welders are suitable for wire to
wire and strio to nut welds. |
