Abstract

This research work is connected to the applicability of laser source in case of brazing of aluminium materials. Based on our earlier research results it become clear that the brazing flux material is able to improve the laser absorption in case CO2 laser source. A new brazing flux material (Fontargen F 400 MD EVO2) and the CO2 laser interactions were investigated to determine the applicability of laser as a heating source. The application of laser strongly depend on the value of absorption of laser energy into the aluminium base material. From our new result it can be seen that the applied flux can improve the laser absorption, thus the laser heating, but the implementation of brazing process with this flux material brings further challenges.
