2584.0. "Alloy Welding" by VYGER::MCKAYRE () Thu Jun 05 1997 17:21

    Hi All
    
    I've got an alloy head that has a crack, it was damaged in a crash
    before I got it. The crack is on the outside and does not affect the
    firing chambers or the oil/water ducts.
    
    The question is how can I get it fixed and will it be easy or nigh on
    impossible ?
    
    According to my sources it is possible to weld alloy but it needs an
    expert. Opinions ...
    
    Finding a replacement is not an option, or at least would be my last
    chance, because they are kind of rare.
    
    Thanx in advance

2584.1Try FROST for DIY solution!CHEFS::HUNTLEY_RThu Jun 05 1997 18:1313
    I beleive it is possible - a friend of mine got a Speedwell A Series
    head repaired but had to send it to Germany. 
    As I remember it was very expensive and took a long time for them to
    return it (two years!!!)
    
    There are some companies in this country selling DIY type solutions -
    Frost Auto Restoration Techniques have a product called Lumiweld, which are
    basically rods that you heat with a Butane blow lamp. It costs �12 for 
    5 rods or �17 for 10. They reckon you can weld heads/blocks etc.
    
    FROST's number is 01706 860338

Aluminium can be welded with a MIG welder with the proper gas and wire.  It
isn't rocket science either.  Now, welding cast iron, that's another issue....

Here in the US there are metal epoxies that I think will work on alimunium that
might be similar to what .1 was talking about, but they don't require a torch.

I wonder if they have Business Unit Managers? :-)

    Thanks for the replies so far.
    
    I'm going to visit a couple of specialist 'head' repair engineering
    companies on Monday so I'll let you know what happens.

Alloy welding will require a specialist. The head will need to be oven heated 
and kept hot and the welding done with an argonised welding tool.

Try a vintage car restorer.
