I am planning to have a new frame built and have yet to decide if I should have it TIG welded or go for fillet brazing.
As far as I can tell from talking to people and hours spent on the internet, that fillet brazing (along with lug construction) was the best way to go years ago.
But now days, TIG is lighter than fillet brazing, and TIG doesn't have the strength problems with air hardening tubing that welding used to have. I have been planning to go with Reynolds 731 or True temper OX which may be more appropriate for use with TIG.
On the plus side for fillet brazing it makes for a smoother looking join, and maybe is stronger(?).
Are there any other arguments in favor of fillet brazing that I should consider, seeing that it can cost $300 - $500 more than TIG.
