Induction brazing of multiple in line aluminum T joints for less than 10 seconds each and brazing an aluminum fitting into an aluminum tube 1.25″ (32mm).
The application is about brazing of an aluminum tube assembly consisting of two parallel tubes with outer diameter of 1.25″ (32mm), wall thickness 0.08″ (2mm) and length between 31.4″ (0.8m) to 86.6″ (2.2m). These tubes are connected in a ladder shape to smaller tubes with outer diameter of 0.7″(18mm), wall thickness 0.05″ (1.5mm) and length. The small tubes have 1.57″ (40mm) distance between each of the smaller tubes.
The application has two types of joints to be made:
Joint 1: “T”-shape joint – between the bigger tube and the smaller tubes.
Joint 2: Joint to braze both ends of the bigger tubes with an aluminum fitting.
