Aluminum Bronze Filler TIG Brazing, again

admin

Until the past couple of days I've never TIG brazed and I'm confused.Half of the info I read makes it sound like you don't melt the base metal (steel), the other half you do. Yeah, I know, “brazing” by definition doesn’t involve melting the base metal, I can't get bare Aluminum bronze A2 filler to flow if I don't puddle the base metal like I'm welding. And... if I do melt the base metal it's a piece of cake and I get a butt kicking joint on any garbage piece of metal I grab. If I don't melt the base metal I get no flow to happen no matter how hot or clean the base metal is. What's the right method?  No guessing please, I'd like to hear from somebody that does Al. Bronze filler TIG brazing on a regular basis.  Thanks much!
Reply:I use Silicon Bronze filler quite often for sheet metal work.I treat it as "standard" welding rather than brazing. Other than amperage settings, I use every method as I would for a weld with steel filler.I have never used Al Bronze.http://all-a-cart.comWelding Cart Kits and accessories
