Brazing vs welding
Hi all. I've done some lurking here and I have a question. Do you all build frames by brazing and torch welding, as opposed to TIG welding?
Is there a post/sticky/website/etc. that tells the basics of what you guys do?
Thanks in advance.

brazing and TIG are both common techniques in high-end custom framebuilding. In my opinion, they are effectively interchangeable. Don't know what other information you want. Torch welding using base metal fusion is not used in mainstream framebuilding AFAIK.

For some reason, I think I like the BF sticky better.

Most people are either doing TIG, Fillet Bazing or Lugs. The last two can be done with a torch which is far cheaper than TIG,and easier to learn.
There are a few people welding with a torch. There is one commercial guy whose URL I used to have. I am working on it, though as usual going about it all wrong, in this case trying to weld with propane as the fuel gas. I also do TIG. I just enjoy horsing around with different methods. I think gas welding has a lot of advantages, the only big problem is whether it creates heat distortion that makes alignment too challenging, I'm not at a point on the learning curve where I can nail down the cause of any of that. It is possible to get it right, just have to keep with it as with anything else. It is a shorter heat cycle than some other torch methods, but it combines greater heat duration than TIG, with a larger area than TIG, but less in both regards than brazing, but higher peak heat.
TIG produces a nicer bead, by far. Maxstar TIG is even better still. TIG creates a very mechanical result, which is partly process induced, and partly skill, it takes both. The gas process is not as mechanical. The welding side of bikes is sorta absent the more encompassing aesthetic one finds in art metal work. When was the last time one saw a hammer finish on the tubing
Not going to happen but the precious rigidity of forms is a bit stiffing.
