1. the welds are not done right, the follow up treatment was poor. The seams are rusting because they were not polished or etched after welding. If you want to be accurate, ask the contractor to show you what is called a welding procedure specification – WPS. It should tell you how the welds should be handled. You can polish the visible side, but you can't polish the top side.
