WEL 145 - Welding Metallurgy (3 CR.)

Course Description

Studies steel classifications, heat treatment procedures, properties of ferrous and non-ferrous metals. Discusses techniques and practices of testing welded joints and destructive/nondestructive, visual magnetic and fluorescent testing. Lecture 3 hours per week.

General Course Purpose

WEL 145 is designed to give a comprehensive picture of the principle arc welding processes so that selection can be made from a knowledge of the advantages and limitations of each process.

Course Prerequisites/Corequisites

None.

Course Objectives

Upon completion of the course the student will be able to:

• explain the purpose and use of material control and fabrication control under the major codes
• understand the weldability of specific alloys
• examine changes in microstructure produced by the process
• identify defects, probability, prevention, and testing

Major Topics to Be Included

• Basic types of metals and respective codes governing welding
• Elements, compounds, and mixtures of metals
• Thermal effects upon the microstructure and physical characteristics of metals
• Weldability and procedure for welding of quench and tempered steels
• Heat treatment of welded metals
