I've tried doing it on other stuff without much success. Commonly used alloys for brazing mild steel have melting points ranging from 1020-1070C (1868-1958F). Regardless of the type, the braze filler metal melts at a temperature above 450C, but always below that of the base materials to be joined. There are several brazing variants, including torch brazing, vacuum brazing, furnace brazing and induction brazing. The main disadvantage of brazing is that it takes longer to complete than other joining methods, such as welding.Additionally, brazed joints are less strong than welded joints, so they may not be suitable for applications where strength is critical. Penetration on tubing and flatwork is the same (if the TIG uses a back-up flux or a back-purge). In furnace brazing, the filler metal is heated in a furnace to its melting temperature and then conveyed to the joint by means of a ceramic rod or another transfer device.
