Endüstriyel Uygulamalar İçin Manyetik Tahribatsız Test Sistemi

Abstract

Levha şeklindeki ferromagnetik malzemelerde yüzey ve yüzeyaltı çatlaklarını belirlemek için yeni bir manyetik tahribatsız test sistemi geliştirilmiştir. Geliştirilen manyetik tahribatsız test sistemi, 3D Tarayıcı sistem ve onun elektronik kontrol ünitesinden oluşmaktadır. 3D tarayıcı sistemdeki sensör, deney sırasında elektronik ünite sayesinde x-y-z koordinatlarında hareket edebilmektedir. Bu makalede, geliştirilen manyetik tahribatsız test sisteminin yapımı, kontrolü ve deneysel sonuçlar ayrıntılı olarak tartışılacaktır

Abstract

A new magnetic non-destructive test system has been investigated to determine surface and under surface cracks in the lamination type of ferromagnetic materials. The investigated magnetic non-destructive test system consists of the 3D scanner mechanic and its electronic control unit. The sensor holder of the scanner system was capable to move on to the x, y, z coordinates during the experimental operation by means of electronics unit. In this paper the construction of the investigated magnetic non-destructive system, its operation principles and experimental results will be discussed

Keywords
