Flexible Manufacturing System - FMS. What is a 'Flexible Manufacturing System - FMS'. A flexible manufacturing system (FMS) is a method for producing goods that is readily adaptable to changes in the product being manufactured, in which machines are able to manufacture parts and in the ability to handle varying levels of production.
When corrosion occurs after the in-process time, the cause may be a corrosive atmosphere. Heat treat departments may exhaust corrosive fumes. One of the most corrosive is sulfur dioxide fumes which will quickly corrode metal surfaces.
However, such steels do contain high levels of sulfur, phosphorus, and lead, which can cause serious welding problems. This is why welding free-machining steels is usually inadvisable. If one of these steels must be welded, the fabricator can try using low-hydrogen electrodes with a basic slag system.The weld metal's low-hydrogen characteristics will reduce the formation of hydrogen sulfide porosity, and the basic slag system reduces the weld metal's sulfur and phosphorus content.Low welding currents can help minimize dilution with the base metal.f one of these steels must be welded, the fabricator can try using low-hydrogen electrodes with a basic slag system.
