How are commercial chain links welded? My first guess is using
resistance
but I would guess the electricity would be more likely to take the
path
around the link than across the touching faces.



In the Black Country, traditionally by hammer welding, and often by
women. Fred Dibnah covered it in one of his programs when he went
round Britain showing lapsed technology after he was diagnosed with
terminal cancer. ~Even huge anchor chains were hammer welded.
