Brazing under an inert protective gas has been in use for a long time. Some of the popular gasses that are a common choice for this controlled atmosphere are nitrogen, hydrogen, argon and dissociated ammonia. Since argon is much more inert than nitrogen, it offers more control. However, it is rather more expensive. The temperature of the process can also affect the performance of the chosen gas. The more commonly chosen is nitrogen for it is more economical. However, it reacts with several of the steels at certain temperatures. Brazing under an inert protective gas is practiced more in specialized large industries.
