Simple yet informative. This channel is soo underrated. I bet anything that comes out of that shop is done right the first time…
I appreciate that!
You chased that one...Good Work..!!!
Thanks 👍
For my tank with a similar leak, After I used silicon bronze, I filled s tub of water and did the leak test with the repair dipped in the water. You just have to look for bubbles.
I found that I had too much amperage/heat in my joints. When I fixed one spot, I accidentally melted the silicon bronze in a different area. I chased leaks until I dropped the heat a bit.
Good job! I would like to know more detailed information about welding wires, such as the model. Thank you
sure! I was using Silicon Bronze filler rod for this repair.
Very nice , I will practice with some silicone bronze, looks like a good arsenal to have, thanks for the video 😀😀
Some years ago, back in the mid-eighties I had a crack in the gas tank on my 1972 Chevrolet 4x4. Well, I did just what you advised and washed out the tank and filled it with water as a precaution. Now I was brazing that crack up with oxy-acetylene and as I got that spot heated up what was left in the tank being fumes the tank goes very slowly "woosh" expands and when I took the heat off it returned to its regular shape. So, I brazed that crack up and all was well. Well upon further reading over the years I read in one publication that a fellow had a gas tank repaired where the tank was filled with exhaust fumes from a running engine before repairing the tank. Of course, the exhaust fumes absorbed the remaining gas fumes in the tank. So fast forward some twenty years and I'm tightening up the rear cab mounts on the same truck and lo and behold I run one up through the same fuel tank (not so smart the rear cab mounting bushings actually need to be replaced) after draining the gas I got the tank out and ran the exhaust from another vehicle in it until it had the tank hot to touch and lo and behold I had no problems repairing the puncture (same process braze with an oxy-acetylene process). For those who disagree, this is the same truck that I have had since 1979 and the gas tank is original, and the truck is parked behind my house as I type this (yes, I still drive it) So, in conclusion exhaust fumes in a tank does work for safety when brazing or soldering a gas tank. Anything hotter will just cause the metal to crack and one will spend eternity chasing cracks. The tig process is of course better than the oxy-acetylene method and of course one can solder up leaks as well. I was afraid that you were going to have to remove that mounting bracket though to get at the root cause of the crack which is most likely from vibration. A good job of repairing the tank and hope it works well for the customer.
Thanks for the information man I appreciate it!!! I hope it will work well for the customer too! I think should be fine. Thanks for watching and taking the time to comment on my video 💯😎👉
I started a Facebook group called "Be a metal fabricator" where you can post cool projects like that! Check it out man!
had to repair my old 650 Bonniville's tank similar spot where the tank bracket bolts to the frame i don't think i will do another. leave it to the professional's like you good vid
yeah sometimes they can be a pain! luckily I was able to get this one done!
Nicely done mate!
Thanks Paul!! Glad you liked it bro!
@paulsanders1373 hey paul I started a Facebook group called "Be a metal fabricator" where we can post, projects, discuss fabrication methods, and showcase our skills with one another. It should be fun man! Hope to see you in there!
I always purge a gas tank with Argon or Argon/CO2 before welding or brazing on it.
Dude that's a great idea! I'll try that n it time!
Bravo
Thank you!
