The steel at the welds by the handles changes it's crystalline structure a bit, due to heat from welding. Same goes for the area around the bowl welds. This causes the steel in those areas to expand & contract slightly differently which causes the enamel coating to crack, letting moisture into those areas, causing rust, which causes the enamel to separate from the steel substrate.That's the simple reason.
