Reply:Yeah I'd say those NUTS aren't going anywhere... Looks good!Every brass piece that I've come across has been pretty 'different', but big hunks of brass seem to be much nicer to weld.  I find that drawing the heat from the Stainless Bolts or Nuts and THEN Into the brass makes welding the two much less dramatic.Fortunately there are a LOT of different flavors of Silicon Bronze and Aluminum Bronze Rod in the market, so TIG'ing Brass, Bronze and Copper and Steel (...and ALL of these to one-another) is much easier and stronger now.Cheers,Miller Diversion 165120 amp Buzz BoxVictor Oxy/Ace Oxy/LPGSmith "Little" Oxy/LPGHypertherm Powermax 30Lot's of Misc. tools n' crap....

Reply:Some of my best guys have trouble making (cast) brass welds look good.  I would say that you did about the best you could in the situation you were given.  Nice work.
Reply:Brass has zink which boils when you arc it. That is what the white soot is from, and the reason the fumes are bad.Silicone bronze tigs well, but if welding brass with it you will still boil the zink. Not to say it can't be done its just not pretty.PeterEquipment:2  old paws2  eyes (that don't look so good)1  bad back
Reply:I have always wanted to try it but dont have the money to spend brass just to put a few welds on.
Reply:Yeah Zinc is nasty stuff and It's pretty foul stuff to breath in...  As it's the only 'Yellow Metal' welders see, it's easy to why so many people get Brass and Bronze confused.  There's no doubt regarding the difference once you attempt to WELD it however...I'm limited to the efficiency of my Brass welds by my hardware and as such, I would definitely use the 'pulse function' on the TIG (if available..), along with strong movements of the pedal.  Welding backwards helps and so does applying the heat directly to the filler rod instead of the 'conventional method' (in front of the Weld Pool).  I've heard of some individuals that use the 'plunge technique', but I personally have never tried that particular method and can see why one would have to use a 'full respirator' when pulling off that trick...Either way, I've seen 'very few' successful 'TIG' welds on Brass and only two individuals for certain that had the ability to consistently WELD brass.  One was a Hand-Rail Builder and the other was a Boat Builder (specifically railings and ornamental's).  Having stated the former, it's my opinion that most of the people that 'assume' they are 'TIG' Welding Brass are in fact only 'sort of' welding it and are really BRAZING it instead... Not that there's 'anything wrong' with brazing, as I myself have been astounded by the incredible strength of a Brazed piece that tears apart the parent metal and leaves the BRAZE intact!Cheers,Last edited by jman; 03-02-2011 at 02:07 AM.Miller Diversion 165120 amp Buzz BoxVictor Oxy/Ace Oxy/LPGSmith "Little" Oxy/LPGHypertherm Powermax 30Lot's of Misc. tools n' crap....
