Use same metal. No SS. Measure the thinkness if you want to know what the thinkness is. Your Flux core is OK for repair. Go slooooooow wait for cool down each spot weld, move all over, blow shop air on it to cool, same when grinding. Thin filler OK.
Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
