Brazing

Brazed joints are made with low melting point, ­conductive silver solders and associated flux. Work with a soft flame, avoiding hard, point shaped, flames and overheating. The surfaces to be joined should be roughened either mechanically or chemically. The brazing gap should be 0,1 mm, the overlap minimum is 2 mm. If you need to join a larger gap (e.g 0,5 – 1,5 mm) we recommend the use of a gap soldering agent, to give strong and stable joins. For Brazing use silver solder with 45 – 56 % silver. Only use cadmium free silver solders in food processing applications. Remove the emerging tarnishing colour by pickling or brushing. Tempering colours can be avoided by adequate wetting and skilful application of heat.
