* Excellent weld quality and a tight seal can be obtained.
* Minimal electrical and thermal contact resistances in the
seams.
* Electronic monitoring of the weld parameters with
interface to central computer for data storage and for
statistical evaluations (SPC).
* Very short welding times (fractions of a second).
* No filler metal necessary.
* Clean and safe process (no sparks, flames and smoke
formation) therefore environmentally friendly.
* Very low energy consumption.
* Can be easily automated and integrated in production
lines.
* Optimum cost / benefit ratio.
