sequently, the copper electrodes wear out
quickly under high temperatures.
“What I saw in Germany when I was with
Magna International was that this Canadi-
an company called Huys Industries had ac-
tually come up with this clever idea of put-
ting a material on the ends of the copper
electrodes, which was titanium carbide,”
Scotchmer said.
Carbides are very hard and titanium has a
high melting temperature. These traits are
opposite those of copper, making them
dissimilar metals. Generally speaking, the
two cannot be welded together since by
the time titanium carbide starts melting,
the copper has already vapourized. Some-
how, Huys accomplished this seemingly
impossible task. The result was this: the
copper electrodes lasted two to four times
longer.
