Weld on cast iron

Posted by Scottf on February 02, 2004 at 11:57:54 from (130.76.32.144):

I just welded up a crack in a cast iron tractor frame. I've welded cast iron many times before without a problem. I know the process and took my time and did right. I used nickel rod. This is the first time the weld was exactly the same color as the cast. Usually the cast is a bit darker. All seemed to go well and it looks good but I noticed something strange. When I pickup some of the some the iron grinding dust from the floor and sprinkle it over the weld the dust attaches in a line were the weld meets the cast. You can see a perfect outline in iron dust of the weld. The dust raised and when you wipe it away you can't see any crack but I was worried that this may be like a magna-flux test showing a crack. Is it possible that the weld has pulled away from the cast?
