Chassis Welding

[Paul S]

Can anyone suggest a good shop to repair the rear sub-frame on a Brabham??? Have a cracked square tube that needs to be cut out and replaced...Car is located in Florida...

May want to find out if it is indeed tig/mig welded or silicon bronze gas welded (brazed).

Many good shops down around there, but you could check with Fred Clark ( Caracal FVs) in Jacksonville. 904-234-5603

If it's a Brabham it is probably welded with Nickel Bronze not Silicon Bronze which is much weaker. This mistake is made all the time, Silicon Bronze is best used for header flanges and does not have the strength that NICKEL Bronze has. Most guys use the silicon bronze because they can use a tig setup whereas Nickel Bronze requires a flux with either a coated rod ( messy, ugly welds) or a gas fluxer which is what was used originally.

I think I found a man to do the repair and it will be gas flux welded..Thanks for the input!!!
