Takım Geometrisinin Yüksek Yoğunluklu Polietilenin Sürtünme Karıştırma Nokta Kaynağına Tesiri

Bu çalışmada yüksek yoğunluklu polietilen levhaların sürtünme karıştırma nokta kaynak birleştirmesinde kullanılan kaynak takım geometrisinin dikiş oluşumu ve kaynak mukavemeti üzerindeki etkileri incelenmiştir. Kaynaklar oda sıcaklığında gerçekleştirilmiştir. Kaynak sırasında oluşan kaynak kuvvetinin ölçümü yapılmıştır. Kaynak dikiş makroyapı incelemesi yapılmıştır. Çekme-makaslama deneyi ile kaynak mukavemeti belirlenmiştir. Yapılan deneyler sonunda takım uc profilinin, uc boyutunun, omuz çapının ve omuz açısının etkileri deneysel olarak tespit edilmiştir. 4 mm kalınlıktaki levhalar için optimum kaynak takım geometrisi saptanmıştır.

Anahtar Kelimeler:

Polietilen kaynağı, sürtünme karıştırma nokta kaynağı, plastiklerin sürtünme karıştırma nokta kaynağı, sürtünme karıştırma kaynak takımı
