EMTL 280 - Welding Metallurgy

Course Description:
As a learner in this course you will consider weld metal solidification and cracking, weld metal microstructure of carbon and low alloy steels, heat affected zone structures, cold cracking, slag metal and gas metal reactions, and lamellar tearing. The learner will also study the metallurgical problems encountered in welding aluminum, stainless steel and their alloys are studied. The use of non-metallic materials and specific processes in the prevention of corrosion after welding is complete is considered. There will be lab assignments in metallographic preparation and examination of weldments. Cross-referenced to the National Technology Benchmarks (NTB).
