N2 - The present paper is devoted to an analysis of clad residue formation during a controlled atmosphere brazing (CAB) process applied to composite aluminium brazing sheets. Evolution of the microstructure of the clad residue, and in particular the mass of resolidified clad formed, were studied. Observations confirmed that, even under optimal brazing conditions, a residue layer (formed away from the joint zone) always appears after brazing. It was established that the peak brazing temperature plays an important role in the process responsible for formation of the residue mass. However, dwell time at the peak brazing temperature does not have a significant influence on clad residue mass accumulation beyond its known influence on substrate dissolution and core metal erosion in the joint zone.
