I asked the chief metallurgist at "Danit", a danish sinter metal
factory, about this recently, He said the conductivity of Tungsten
carbides is in the range of 1/10 to that of copper.
I take that as an argument for brazing short pieces of the welding rod
to copper sticks, and then have them machined afterwards.
A very big snip :-)
