Investigation of Fume Formation Rate in SMAW of 316L Stainless Steel with Different Electrodes Using Taguchi and Anova

Kaynak, kolay uygulanabilirliğinden ve mukavemetinden dolayı, imalat sektörü ve ağır sanayide en çok kullanılan birleştirme yöntemlerinden birisidir. 316L kalite paslanmaz çeliklerin başlıca kullanım alanları kimya, petro-kimya, gıda, kağıt, boya ve gemi imalatıdır. Paslanmaz çeliklerin kaynağında ark kaynak prosesleri tercih edilmektedir ve gazaltı kaynağının yanında örtülü elektrotla ark kaynağı da sıklıkla kullanılmaktadır. Kaynak prosesinin avantajlarının yanında bazı dezavantajları da vardır. Kaynak, toksik duman ve sağlığa zararlı gazlar oluşturduğu için iş sağlığı ve güvenliği ile çevre açısından tehlikeli bir proses olarak tanımlanmaktadır. Bu çalışmada, Taguchi deneysel tasarımı oluşturulmuş ve iki farklı markanın aynı sınıflandırmaya sahip elektrotları, farklı akım parametreleri kullanılarak 316L paslanmaz çeliğin örtülü elektrot ark kaynağında kullanılmıştır. Her deney şartındaki duman oluşum hızları ölçülmüş ve sonuçlar Taguchi sinyal-gürültü oranı ve varyans analizi ile değerlendirilmiştir

Investigation of Fume Formation Rate in SMAW of 316L Stainless Steel with Different Electrodes Using Taguchi and Anova

Welding is one of the most utilized joining techniques in heavy industry and manufacturing sector due to its ease of application and strength. 316L grade stainless steel is mainly used in chemical, petro-chemical, food, paper, paint and shipbuilding industries as well as dairy equipment. Arc welding processes are preferred in joining of stainless steel and shielded metal arc welding is widely used in this respect along with gas metal arc welding. There are some drawbacks of welding despite many advantages. Welding is defined as a hazardous process in terms of occupational safety and health and the environment because of toxic fume and noxious gases emitted. In this study, Taguchi design of experiment was utilized and shielded metal arc welding of 316L grade stainless steel was realized using electrodes with same classification from two different brands with different current parameters. Fume formation rates for each experimental condition were measured and results were evaluated using Taguchi signal to noise ratios and analysis of variance.
