| May 1, 2020 at 3:19 | comment | added | Daniel R Hicks | It's unclear from the video what materials he's using when -- steel, aluminum, titanium. And I did not see him using a torch which appears hot enough to weld, though I can't say for sure. | |

| May 1, 2020 at 2:53 | comment | added | whatsisname | @justin: it's possible, but its challenging. The difference in time for getting the joint hot enough to wet the metal and hot enough to "overcook" it is pretty slim. | |

| May 1, 2020 at 2:39 | comment | added | justin | In GCN's video about Agustin Hincape, it showed him using what looks like an oxy-acetylene torch to fillet braze. The tubes looked like they were getting red hot. Is fillet brazing impossible with heat treated tubes? | |
| May 1, 2020 at 1:01 | comment | added | Daniel R Hicks | Brazing, on the other hand, does not use temps high enough to damage the steel tubing, unless badly botched. This is why brazed "lugs" were used to fasten together better-quality bike frames prior to the invention of rapid welding. | |
| May 1, 2020 at 0:58 | comment | added | Daniel R Hicks | Welding does ruin the heat treating, if done improperly. But 30-40 years ago manufacturers developed the technique of welding very rapidly, to minimize the damage. Cannondale invented the technique, first to put together aluminum frames, but it was adapted to steel. | |
