John, I have only used flux when using it on cast iron, both the cast flux and brazing flux worked. other than that, its fluxless. easier to not melt the steel with a torch too, if thats the goal at hand.

copsiloy
Folks,
Many years ago i got a lot of different type rods out of a welding shop in a plant where I bought my large southbend lathe and my Bridgeport mill. In the mix were rods that had copsiloy stamped in the rods. I used them to close up some holes in an old sprint car frame. It flowed into 3/8 holes and has held up great for many years. Do any of you people know anything about these rods or have ever heard of them?

I used it to weld the body panels to the frame structure on my Dwarf Car. I crashed around a lot in that thing and I don't recall any of the joints popping loose. The body is 24 gage aluminized steel. Frame is 1/8" wall steel tube.

We are using a mig welder and the silicon bronze wire to weld in door surrounds and section frame rails that are on newer cars. Many 08 and newer autos use Boron steel to lighten the structure yet make it stiffer. Welding with steel mig wire makes the weld area brittle and subject to stress cracking.

Reason why I ask is that I haven't been to collision training for about 7 years. When I went to my last ICAR classes, we were told not to touch a modern HSS frame. Just replace them. Maybe today's uni-structures are totally different than the truck's hydro-formed frames we were learning at the time.
