• There was an arc welding system used briefly after the war (I think) that didn't use any filler material, the tubes were pushed together at high pressure and then a high current was passed through them that fused them together at the joints. It never really caught on, I'm guessing the tooling was not versatile enough for the bike industry.

  • I think the post war welding process Dallas refers to is known as flash butt welding. Dayton used it, but their frames had a reputation for breaking - so maybe that's why it didn't catch on.
