WLD 151 - Fundamentals of Metallurgy
Physical, chemical and mechanical nature of carbon and alloy steels. Includes study of the purpose and practice of various thermal treatments and cold working processes common to metal using industries.
Prerequisite: RD 087 and EL 115 OR prior college OR placement test.
Upon successful completion of this course, the student should be able to:
1. Identify various types of the more common commercial metals by two or more methods.
2. Describe the basic atomic and crystalline structure of metals.
3. Describe at least five mechanical, physical, and chemical properties of metals.
4. Describe the effects of alloying elements.
5. Perform the heat-treating processes of annealing, normalizing, quench hardening, tempering, stress relieving and other metal working processes.
6. Explain the effects of expansion and contraction during temperature changes in structural shapes, fabricated frames and machinery.
7. Determine the weld ability of various metals and describe an appropriate welding procedure and process for those metals.
8. Demonstrate or describe processes and applicability of preheating and post heating for various metals.
9. Describe fluxes, slags, and shielding gases and their effects on weldments.
