Welding Unibody Seams?

[Wade Mahaffey]

Tom, the floor panels, firewall, dash, as well as other panels thruout the car built by pro builders is a light duty area. It is just a panel covering some frame/chassis structure. This practice has been done for a very long time, but the panels are not there for chassis design and/or strength. The silicon-bronze is used because of it's low melting point to keep high heat off of the 4130 moly tubing. Now SlB is fine for that, But not for reinforcing unibody construction in my opinion. As far as aircraft, years of knowledge, skill, proper equitment, testing and evaluation, quaility raw materials are things the average back yard builder does not have, so I would not reccomend that direction IMO. I started welding with Silicon-bronze 40+ years ago and I have experience and my opinion in what it can and can't do.
