Al7039 Zırh Plakalarına Sürtünme Karıştırma Kaynağı Öncesi Uygulanan Ön Isıtmanın Geliştirici Etkileri

Abstract

Abstract: In this study, Al7039 plates at certain dimensions were first joined via friction stir welding (FSW)method at room temperature. During this process, thermocouple tips positioned closely to the each side of theweld helped determine temperatures on the advancing and retreating sides. These temperature values were usedto estimate pre-heating temperature of the base metal prior to the welding process. After Al7039 plates atidentical dimensions were heated to a certain temperature, they were joined using the same welding parameters,and the heat distribution was determined thanks to the thermocouples positioned on the same zones. The heatdistribution between two samples which were joined using different heat inputs were analyzed to reveal theimpact of this heat distribution on the weld zone via mechanical tests and micro structure images.
