I am not familiar with welding stainless steel
. My water tanks are 28 years old and are seeping at the spot welds where the baffles are tabbed to the tank wall as well as along some of the welded seams. I am in a location without a marine
industry and dealing with workers in a language a second language for both of us. They did some re-welding along the seams and the tank is leaking around their repairs
, perhaps at an even faster rate than it was before.
The company here now says that my tanks are too old to fix! They say will have to fabricate new tanks for me. From the look of the tank that I managed to remove, it had not been previously repaired. They re-welded the area where the seam was leaking and not the whole length of the seam.
I have some questions.
[*]Is this true about stainless steel
? Will it become to thin to work with? Is it possible that the re-welding that leaked was poor workmanship or material failure?[*]Is there a specific method or equipment
that should be used to make this sort of repair?[*]If I have to have a tank fabricated, what thickness steel should a 45 gal/200 l tank be? The shop here says 2mm!
For those who have used JB - weld. Is safe for drinking water
tanks? do you apply to the outside or inside?
Any advice or pointers will be greatly appreciated.
