Course Objective

Stainless steels, nickel and its alloys and monel are inevitable and important materials for the industrial applications. Those materials are becoming more important nowadays. Therefore, those materials are used constructions. Microstructure and mechanical properties must be known correctly because of that those constructions are used safely in the system. Welding techniques such as gas metal arc welding (GMAW), Gas tungsten arc welding (GTAW) and laser welding have become more important place in current developing industrial areas. The post graduate students in the Mechanical Engineering and Metal Education possibly will be joined into industry need to know about those subjects both technical and practical way. Thus, the aim of the course is to give the student confidence with knowledge technically and practically of the subjects.
