Constitution and structure of cast and welded alloys. Solidification and heat treatment of casting. Welding codes and specifications. Properties of cast and welded components. Design considerations for casting and weldments. 

Pre-requisite    :    MENG 339 Fundamental Manufacturing Processes 

Pre-requisite by topic:
    Students entering this course should understand and the knowledge of:

• Classes of materials and their properties.
• Basic mechanical behavior of materials using destructive testing methods.
• The fundamental laws and techniques of elastic st rength of materials: Hooke’s Law.
• Stress/Strain behavior of materials under the various loading modes.
• Manufacturing methods and processing of materials

Objectives

Upon the completion of the course:
1. Students should demonstrate an undeerstanding of the relatsionship of the solidification parameters with the microstructural features and its effect on the mechanical properties of cast metals and alloys.
2. Students should demonstrate an understanding of the design considerations and the necessary heat treatments essential for preventing defects associated with the various casting processes.
3. Students should be able to identify the welding defects (using both destructive and non-destructive testing), their causes and prevention.
4. Student should be able to design welded joints.

Course Outcomes:
After co mpleting this course, students should be able to:
1.Control the cast product mechanical properties through controlling the solidification parametres for the various applications. 
2. Identify and prevent casting defects either by the various design considerations, or heat treatments.
3. Design, and manufacture a cast product based on the above knowledge
4. Use destructive and nondestructive testing in determining cast and weldments properties and identify the formed defects for the vario us kinds of welding techniques
5. To design welded joints geometry, and welding technique based on the materials to be joined.
