I need to weld to drill rods together .06" diameter, what is the best way to do this?
---------------------------------------------------
drill rods will be hard and brittle if welded without extensive preheat and post weld heat treatment and its not practical for most applications.
is it possible to use a sleeve coupling and silver braze?
if this is a high volume job, then it is possible that a benchtop pulse yag laser welder might work.
it just depend on the application.
