I'm considering MIG Brazing in a set of steel GTS flares soon and wondered if anyone has experience doing this on a Pantera. MIG Brazing is used on the newest cars from Jaguar, Honda and others in non-structural areas because the lower temps don't compromise the steel or the rust proofing. You will find most roof panels on newer cars are MIG Brazed on with little or no lead used. The lower heat also reduces warping of the steel compared to regular MIG welding which means less overall bodywork to finish. MIG brazing looks to have 60% of the tensile strength of regular MIG welds but only requires less than 50% of the heat of a fusion weld. ICAR requires it for certain new car repair certifications.
I have done some Mig brazing before and it seems to work well on mild steel sheet metal. Anybody else have experience with it?
