It is characterized by the use of filler materials with melting temperatures lower than 450°C and by modest result of mechanical resistance.
It is characterized by the use of filler materials with melting temperatures lower than 450°C. depending on the required characteristics and the metals to be welded, various alloys can be used. Alloy silver based, copper and zinc with a melting temperature between 600°C and 700°C are used for the brazing of carbon steels and copper alloys. Copper is used for carbon steel and stainless steels brazing. For stainless steel brazing and alloys with high nickel level are also used nickel-based alloy.
It is characterized by the use of filler materials with melting temperatures higher than the Strong Brazing but in any case, lower than the melting point of the joint materials. Joints preparation is often similar to the autogenous welding. Commonly used alloys are melting brasses at relatively high temperatures (800°C). The process is not based on capillary attraction, but mainly on the atomic diffusion of the filler alloy in the intergranular structure of the base material.
