      As long as a cast part you are trying to repair is not constricted while welding I find the result are usually favorable as the part is able expand while welding and contract while cooling. When trying to weld a constricted part like a crack in the side of a cast engine block, you are very likely to have cracking occur as the expanding cast iron can't go anywhere it thickens instead, then while cooling it try's to contract back to its original position but instead pulls on the rest of the casting enough to crack.
