    Low melt Alum. welding rods.

    Reply for Bogmaster.

    Not sure if this is correct procedure to reply to your email but.

    The low melt aluminium welding rods are distributed by a crowd
    called Lavere Products of P.O. Box 50 Taralga, NSW 2580 and
    phone and Fax (02) 4840 2017, under the product name of
    ULTRA BOND, about 18 months ago the price of the rods were
    bundle of 5 rods $11, 12 rods $22 with postage $4.40 and for
    35 rods $55 and 1kg $71.50 with postage $6.60 all prices including
    GST.

    Not cheap, but like everyone else I was intrigued with their demo, and
    must have been flush with funds as I got the 1 kg special at the show
    they include a comprehensive set of directions and recommend cleaning
    the area to be welded with a stainless steel wire brush they also sold.

    They use propane for weld heat, I have oxy acetylene which may be
    a bit too hot. I thought it may be useful in welding pinholes in Air con
    or repairing the cross threading you get on air con coolers.

    Hope the address helps.

    I think they get to a lot of shows with this stuff... I've seen it a couple of times in Brisbane. There are local dealers all around, I think.

    Ray,

    I would suspect this is the stuff that "Dillon" welders used to use for demo purposes a few years ago when they would weld a coke can back together and so on.
    Anyone using it to weld up corrosion holes in air/con pipes would need to have more spare time than I'd be likely to have, the patience of Job and be a scholar of the Dale Carnegie's School of positive thinking to attempt it as one corrosion hole usually says "I am not alone" and has a lot of friends for company once the pipe is cleaned up well enough to be able to weld it.
    If it's the stuff I have used, it works on the melting point of the flux; once this starts to puddle, it's time to hit it with the rod. Is handy stuff given the right set of circumstances.

    How would it go filling non-critical areas in corroded heads?

    I wondered this when I was watching the demo.

    In researching stuff for the E-Type resto (which was started for the first time at Christmas dance ) I noticed Frost (a UK restoration specialist) sell a kit called Lumiweld, which it's claimed can weld any type of aluminium alloy, including dural, birmabrite (ie. Landie panels) zinc alloys and that crappy Mazak. I assume this is the same stuff. In the catalogue they show a casting like a water pump that's been welded back together across a clean break of about 40mm in length, so I assume a head would be OK. It can be used with a butane torch, which I think isn't as hot as propane. Sounds like good stuff.

    Ray and Stuey

    The pamphlett I have here lists all sorts of repairs Ultra bond can do
    including Alloy Heads, Stripped Threads, Refrigerators, Vac Cleaners, gears,
    pumps, dies,carburettors, radiators etc etc. I bought it specifically to
    (eventually) (one wet rainy day when I have nothing else to do!!) repair
    the cross threading of the pipe inlet and outlet (cut off the cross threaded
    hexagon part and weld up thread then re- thread on the lathe and weld back
    onto the pipe. I am confident the material will do the job, but just wondered if
    anyone else had used the product. On patience and welding, quite a few years
    back I used to throw away good exhaust systems until a new Zealand visitor
    showed me how to weld them and get at least 3 more years out of most systems,
    so after spending many hours welding up feathery iron piping, I am sure with a bit
    of patience (my wife would laught at that!!) I will be able to weld up pin holes
    in the Aluminium aircon pipes if required...

    Ken,
    FWIW I have used it as I said, the thing as I've tried to explain is that to use it on aluminium refrigeration piping may sound easy in the brochure but in reality I have seen coroded pipes have up to 50 holes in less than a foot which was why I said you'd need the patience of Job and a lot of misplaced confidence. In the refrigeration trade it was sometimes used on situations when a hamfisted housewife or her husband had attacked the freezer with a knife & poked it through the side whilst attempting an instant defrost. Modern epoxies basically rendered it obsolete.
    With todays legislations on these things as well as labour costs, I have doubts it is really a viable proposition.
    If you do decide to give it a go, please let us know how you get on...just hide the poison, knives, guns and get the gas turned off before you start because I get the feeling that the frustration could have you going looking for them, but if you think it's not a problem, hey; go for it.

    Alan S cheers!

    Thanks Ken,

    Taralga isn't too far up the road from here. I'll give these characters a ring. I have spent a fair bit of time trying to track the stuff down on the net, in rural newspapers and on foot at shows ....but figured I had missed the boat, so thanks again Ken. head_ban
