I have looked for an answer to this question but have not found a good answer, at least so far, so I thought I would ask here. I have a 300 gallon water tank for a well. It's starting to leak in a few spots right near the bottom. I thought I would have to replace it but then thought, why not just repair the spots that are leaking instead of buying a whole new tank.
I have since learned that welding galvanized isn't so easy due to the toxic fumes it produces. Apparently stick or O/A aren't the way to go and Mig is the best process to use. My question is how do I do this repair? Do I weld a new piece of steel over each of the leaking spots or do I try to apply the welds directly over the weak spots? Do I have to remove the rusted metal and make a hole where the leaks are first or leave it alone? Is Mig what I should use for this job even though it will be done outside onsite and it may be windy? Anybody know how to do this kind of job? Thanks.
