<VV> Re: Mig brazing > TIG brazing

[djtcz at comcast.net]

I knew of 2 guys that did TIG brazing for  the same advantages as Oxy acetylene bronze welding.  Bronze is stretchier so less prone to cracking in restrained joints.  brazing temp is lower so Base material does not melt, and metallurgy is not so messed up, and overall there is less (but still plenty) distorton.  The TIG heat was so quick that it tended to be less prone to cracking than OA.  The application was welding up pressfitted motorcycle crankshafts that tended to twist under drag racing abuse.  Harley, Kawasaki and Suzuki

I had not heard of MIG brazing, but Google (as usual) came thru in a flash and found this.
