| Abstract Scope |
Ultrasonic metal welding (USMW) is a solid-state welding technology that is used primarily in electrical and electronic applications, including aluminum wire connections for modern automobiles. From the manufacturing to the welding process, aluminum stranded wires are subjected to numerous potential influences that affect their final state and therefore welding quality, such as the time-dependent formation of oxide layers as well as contamination during production, transportation, and storage. Current research is focused on the influence of contaminations and oxide layer properties on the ultrasonic welding quality of EN AW-1070 aluminum stranded wires. Wires were systematically stored under different environmental conditions to study the influence of contamination sources (temperature, humidity, insulation materials degradation) on the welding quality. Preliminary studies demonstrated that humidity and storage temperature are decisive factors in the properties after welding. In contrast, insulation material degradation plays a minor influence on the process and properties. |
