WLD 154 - Welding Metallurgy

Institution:
Delaware County Community College
Subject:
Welding
Description:
As an introduction to metallurgy, this course helps students develop an understanding of basic metallurgical principles as they apply to fusion welding to improve quality of workmanship in the field of welding. The course material will cover the chemical, physical and mechanical properties of metals as applied to welding applications. Welding metallurgy for welders will cover heat treating processes for metals, physical and mechanical properties of metals, metal identification, carbon equivalency, filler metal selection, heat input and its effects on the weld zone (HAZ) and the effects of heat treating and stress relieving applications within the welding field. Upon successful completion of this course, students should be able to: Define the practical aspects of metallurgy; Identify the fundamental principles and practices of welding metallurgy; Identify the composition and classification of base metals; Explain the physical characteristics and mechanical properties of metals; Identify grain structures and hardfacing of a weldment; Demonstrate field identification methods of base metals; Demonstrate preheat, postheat and postweld heat treatment of metals; Identify hydrogen cracking and its effect on welds; Identify metallurgical considerations for welding ferrous and non-ferrous metals; Identify various heat treating processes and their effects on metals.
