The old joke "... if I was going there, I wouldn't start from here ... " comes to mind.

Given the requirements of your final product, can't you start with some better material? Save the Swiss cheese for a less demanding application.

in the metal business we have to certify "no weld repair."

I'm thinking you need a similar standard.

It would be just my luck thatyou are doing this to salvage rejected electrodes that I buy for my electric arc furnace and your repairs blow out as soon as charged.

Not big fan of repairing ; like to use controlled processes to prevent need for repairs. Think improvement, not repair.
