Controlled Atmosphere Aluminium Brazing in Laboratory Glass Furnace
Purpose
Testing brazing characteristics and properties for different combinations.
Procedure
Two different parts made of aluminium alloys (coupon 25 mm x 25 mm and angle shaped stripe) are coated with flux, dried and brazed in a laboratory glass furnace. The brazing process can be filmed (video recorded) upon request.
The furnace heating control allows different linear heating rates and dwell times at any temperature to be applied.
Standard brazing heating profile
Heating rate – 30 °C/min up to 605 °C Dwell time – 2 minutes at 605 °C, Cooling rate – approx. 30 °C/min
The single unit test involves the following:
Preparation of brazing sample (one coupon and one angle), coating of sample with flux (Solvay’s material and the clients materials can be used), brazing , optional recording by real time movie, and report. Brazing is evaluated by an arbitrary scale from 1 to 5, where 5 is very good.
