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

DVS-TV was underway at the Congress Aluminium Brazing in Düsseldorf, Germany, which took place in June 2014. The interesting video report is online since July. Among other things, coverage included Solvay’s presence and an interview with Dr. Hans-Walter Swidersky. Watch the video.

Electrostatic Fluxing – Additional Information

Jul 21
2014

Additional information to the Article Flux Application: Electrostatic Fluxing In dry flux application, the flux powder is electrostatically charged (typical voltage is ~ 100 kV) and applied to a grounded work piece. An electrical field results in flux deposition of the work piece. In practice, anisotropic distribution of the electric field can influence the homogeneity

Brazing of Aluminium Alloys with
Higher Magnesium Content using Non-Corrosive Fluxes – Part 5

Jul 15
2014

Technical Information by Leszek Orman, Hans-Walter Swidersky and Daniel Lauzon Abstract For just as long as aluminium has been used for brazing heat exchangers, there has been a trend to down-gauging components for weight savings. The most common alloying element to achieve higher strength alloys for the purpose of down-gauging is magnesium. While magnesium additions
