Flux Paints and Pastes – Part 1

Jun 11
2015

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

Flux-Green-Filler-Stop – This far, but no further

Mar 27
2015

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

Aluminium Brazing –
System Design for Temperature Profilers

Feb 04
2015

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
