Rusted Posted January 5, 2011 Share Posted January 5, 2011 Looking at lead sled ute. Through gold braze welds would look epic when replacing the current bog repairs. All cool? Cu-Zn (brass): General purpose, used for joining steel and cast iron. Corrosion resistance usually inadequate for copper, silicon bronze, copper-nickel, and stainless steel. Reasonably ductile. High vapor pressure due to volatile zinc, unsuitable for furnace brazing. Copper-rich alloys prone to stress cracking by ammonia. Quote Link to comment Share on other sites More sharing options...

JasonK Posted January 5, 2011 Share Posted January 5, 2011 you will get distortion in the panel due to the heat used as you do with any welding. some factory welds on older cars are brazed however Quote Link to comment Share on other sites More sharing options...
QCADTA Posted January 5, 2011 Share Posted January 5, 2011 and its exspensive compared to a mig. and if you want a period look you might as well do some lead wiping instead of bog, makes you appreciate how easy bog is. Quote Link to comment Share on other sites More sharing options...
Rusted Posted January 5, 2011 Author Share Posted January 5, 2011 Warping and distorting are good things for this project. Whats the deal with bottles for oxy cet? Still gotta rent of Bunch Of Cunts (BOC) or likes? Or, LPG welding suitably? Also more info on lead work. I have a series of big ugly brass lead working things and a bucket of lead.

Seedy Al Posted January 5, 2011 Share Posted January 5, 2011 only thing that wont really matter, is that like any two different types of steel will rust quicker when in contact with moister due to battery effect Allan Quote Link to comment Share on other sites More sharing options...

KKtrips Posted January 5, 2011 Share Posted January 5, 2011 Lead filling is a little bit different to just getting some old wheel weights and melting them into the hole - I believe its a special compound of lead Note - it is extremely toxic to do - as in its not surprising that you don't find that many panelbeaters in their 80's.. When I have a little more time this avo I'll dig up some sweet info for you.. see if it is your thing. But it involves heating lead to about as thick as a moist cake mixture then using a wax covered paddle you push it around the steel and into the holes etc - all while keeping the lead malleable with heat. Then once it is aprox the shape and places you want you let it cool and then file it with a variety of files to the final shape. Essentially its just like soldering on a large scale - it behaves like bog but is less compliant and you use files to shape it rather than sandpaper..

KKtrips Posted January 5, 2011 Share Posted January 5, 2011 PS: in answer to your question - brazing is OK for filling instead of bog if you use an appropriate heatsink paste to prevent acres of warpage but it has no structural integrity so its a no no for important structural members like pillars and around door handles/hinges..

Rusted Posted January 5, 2011 Author Share Posted January 5, 2011 Gutter rails and pillars is where the work is required. Plain. Quote Link to comment Share on other sites More sharing options...
yoeddynz Posted January 6, 2011 Share Posted January 6, 2011 with bike frames the old school fillet brazed frames are immensely strong- in fact the joins wont break- the tubes will. I would have thought it would be strong enough for pillars etc but yeah the testers dont like it- here or in blighty. But would they know anyway once its covered in paint. Bronze is expensive though. I'm sure my rx3 had brazed together sections- near the windows? Quote Link to comment Share on other sites More sharing options...

Braze welding is only structural if your fusing the base metal together, all the older cars that iv'e uncovered braze joins on have had underlying spot welds, and the braze was just to fill a seam and negate the need for seam sealer.

Rusted Posted January 6, 2011 Author Share Posted January 6, 2011 Take several pieces of scrap metal. Tack together with spot welder then reinforce with brazw welds then MIG said piece to gutter rail? Quote Link to comment Share on other sites More sharing options...
