Ultrasonik horn çatlama nedenleri

Ultrasonik Horn çatlama sebeplerine geçmeden önce titreşimi oluşturan vibrasyon grubunu kısaca tanıyalım; Ultrasonik vibrasyon grubu 3 ana elementten oluşur. Bunlar, kristal dediğimiz çevirici, booster ve ultrasonik horndur. Ultrasonik kaynak makinasının verimliliğini etkileyen en önemli unsurlardan bir tanesi bu elementler arasındaki yüzey uyumudur. Birbirine temas eden yüzeyler arasında zayıf bağlantı varsa ya da yüzeylerden biri düzgün olmayan (diğer yüzeye göre paralel olmayan) bir yapıdaysa ultrasonik titreşimler tam olarak aktarılamaz, güç kaynağının elektriksel verimi düşer, kaynak esnasında ses seviyeleri yükselir ve genelde elementlerden biri mekanik deformasyona uğrayarak bozulur. Endüstride, ultrasonik kaynak işlemlerinde en sık karşılaşılan sorun horn çatlamasıdır. 

Ultrasonik horn çatlamasının sebepleri kısaca şöyle özetlenebilir; 

• Metalin metale sürtmesi, 

• Zamanla metalin yorulması,

• Ultrasonik horn tasarımındaki hatalar o keskin köşeler, o slot tasarım hataları o doğru frekansa ayarlayamama 

• Ultrasonik Hornu, booster ile aşırı sürme

• Ultrasonik Hornu, boostera aşırı sıkma 

• Ultrasonik Horn içindeki vidayı aşırı sıkma

• Ultrasonik Horn malzemesinin içindeki görünmeyen çatlaklar

• Ultrasonik kaynak operasyonu esnasında aşırı basınç uygulama
