I am not an expert O/A craftsman but I do have experience putting panels on cars and other "light" duty O/A welding. I have also done a lot of brazing. I think it is harder to control the brazing puddle than it is the welding puddle. The brazing gets away from me much faster. I have a better track record of things staying together in a high vibration environment when I braze. My Dad used to laugh at me when I was a teenager. He used to say that there was more braze on the floor than on the joint I was working on. I think that TIG would be a challenge that I would like to try.
