  2. Jaf frame crack situation

    Interesting talk about Bronze welding, when I first started work making furnaces we made one for a company making bike frames. The prepared tubes went into the furnace and came out bronze welded,every joint was push fitted beforehand so a lot of preparation involved. It is a strong method of manufacture but for handmade frames not really practical unless you spend a great deal. Manufactures like Reynolds still recommend Bronze welding as well as TIG.

    But the to be fair if I was paying 300 odd pound for a custom frame and knew that bronze welding was better I would want it done.. No matter what extra preparation

    In my trade nothing's brazed . Tig is a really strong weld ' an inch weld should hold a tonne in weight .

    Also brazing /gas welding is we're tig welding originated from .

    Before tig there was gas welding it's basically a crude less refined way of tig welding.

    Bronze braising/ gas welding is a strong weld I agree and the bronze it self is soft witch allows the joint to flex a little more without cracking + the fact that the weld is at least 4 times wider than most tig welds on a bike frame.

    I can tig/gas weld / braise so it will be down to customer choice

    But in the grand scheme of things tig is best in my opinion .

    Strong

    Clean

    Less perpetration time

    And bronze/silver solder rods are mega expensive too

    Ur right about the heat though it uses less heat to braise than it does to tig weld witch is good for not putting residual stress in the metal

    Other than that I can't offer any more I hope this helps

    Thanks for the detailed reply, alot off what you say makes sense, I do see that tig is a cleaner weld and less messy. I heard that braize is harder weld than tig? If there was the option I think I would choose braize from my knoledge on it in the agricultural trade.. And the fact the weld will flex more is better surely? Less likely to crack on the welds like every other frame does. Rhys

    Just I'm an engineer apprentis and was bronze welding at college this week, and I my tutor was telling us that bronze welding it much stronger Thant tig or mig and also flexier.. And he said that all bike frames would be better brazed, it's so easy to do as well and uses less heat and doesn't corrod

    As im here before him, its tig tastic. Migging ally is pretty pants, and high grade steels are just asking for it! :)20130927_140527_zps7b81cd92.jpg

    Mig looks like this fairly crude example20130927_141051_zps85a6fecf.jpg

    *edit bad pic wire brush n come again

    so you even tig weld the steel? not mig? why not bronze weld it? stronger surely
