The Theory and Practice of the Flame- and Furnace-Brazing of Aluminium Dates: September 6 & 7, 2016 in Hannover/Germany Purpose of the Seminar: This technical training seminar will be presented in the English language at the Conference Centre and laboratories of Solvay GmbH, in Hannover, Germany. It will provide information concerning the
Looking for alternatives of a standard aluminium brazing process with a lower level of nitrogen consumption or you are involved in the process of heat exchangers manufacturing, especially in the automotive and aftermarket, don’t miss the Webinar. SECO/WARWICK guarantee a high quality of brazing process of elements, especially for unique types of aluminium heat exchangers.
What is critical Have a clean surface (free of dust, grease) Heat the joint evenly to brazing Temperature Choose the right brazing alloy for the job (Mg content !) Select the appropriate flux to remove the oxide skin from the faying surfaces of the joint Use a capillary gap of the appropriate size ALUMINIUM BRAZING
U‐shape brazing alloys with flux integrated into material Advantages Reduced labor cost Reduced waste No post-braze cleaning Flexible design Multiple applications Ideal geometry for feeding No hidden flux voids Precise control of alloy and flux Ideal for Preforms Unlimited preform options Flux flows unobstructed NON‐CORROSIVE FLUX No post braze cleaning required, reducing the environmental
Selecting the Correct Flux –WHAT? The first requirement of an Aluminium brazing is to be chemically effective. Fluxes are categorized as active (corrosive) and inert (noncorrosive). Fluoride base fluxes → NON‐CORROSIVE The fluxes leave the white gritty residue on the part. These fluxes include the higher temperature potassium aluminium fluoride and the lower activated cesium
Aluminium joining – Brazing ‐ Flux function What is brazing? Brazing is the joining of metals using a molten filler metal. On melting, the filler metal spreads between the closely fitted surfaces, forms a fillet around the joint and on cooling forms a metallurgical bond. By technical definition ‘brazing’ is a joining process in which the filler metal
On October 13th and 14, 2015, the European Association for Brazing and Soldering (EABS) together with experts from Solvay Fluor and Solvay Flux, has held the 14th annual Technical Seminar on the Theory and Practice of Flame and Furnace Aluminium Brazing – short: The Aluminium Brazing Seminar. The delegates were representing technical staff, design
