Welcome to the aluminium brazing blog site. We will regularly be publishing articles about aluminium brazing in this blog and we look forward to your comments, remarks and questions. Behind the scenes in this blog are the specialists for aluminium brazing from SOLVAY. This blog is a corporate blog and offers you new, additional ways to communicate with us.
Part: 1: Flux Paints and Pastes – Part 1 Flux and Braze Paste Characteristics The purpose of flux and/or braze pastes is to provide an initial or supplemental volume of flux and/or filler metal in the form of a viscous liquid at or near the interface of two components: Folded tube seams Tube to header joints […]
Concept and Definitions In addition to the standard methods of applying flux to heat exchanger components (wet fluxing and dry fluxing), there is an increasing trend to using sophisticated flux formulations for selective pre-fluxing of components and/or localized fluxing of complicated geometries. The driving force behind this trend is multi-faceted: heat exchanger manufacturers are seeking […]
EABS and Solvay Special Chem announce the thirteenth annual presentation of their joint technical training seminar. Dates: 13th and 14th October 2015 Purpose of the Seminar: This technical training seminar will be presented in English at the Conference Centre and laboratories of SOLVAY GmbH, in Hannover, Germany. It will provide information concerning the manufacturing practices […]
Flux-Green-Filler-Stop (GFS) “stops” molten brazing filler metal from flowing into areas where it is unwanted, thus the surfaces remain clean and free from the presence of any filler metal. Brazing filler metals do not like to bond with, or flow over, any dirt, grease, or oxides so the presence of any of such contaminants can […]
Brazing aluminum products such as radiators, condensers, evaporators, etc. for the auto industry is a mass production process. The brazing operation is generally carried out in a mesh belt furnace under a nitrogen atmosphere and is commonly known as ‘CAB’ – Controlled Atmosphere Brazing. Accurate temperature measurement of the product throughout the furnace can be […]
