One of the most important factors in cooling systems is ensuring tightness. For this, it is necessary to form strong aluminum copper pipe connections. These connections working under vibration should not leak during long-term use. In this study, aluminum and copper pipes joined by eutectic welding and brazing method were investigated. Tensile test, impermeability and bursting tests were applied to all samples. Microstructures at the junction interfaces were investigated under scanning electron microscopy (SEM). As a result of the experimental studies, eutectic welding and brazing connections were compared. Although the eutectic weld joint length is 50% shorter than the brazed joint, the tensile test gave approximately the same value of 22 N/mm2. In the blast tests, on the other hand, the eutectic source showed 16.67% higher pressure resistance.
