Welding - WELD 262

Course Description

Welding metallurgy includes the influence of alloy composition, filler materials, fluxes and thermal interactions on the structure and properties of metals. Topics covered in the course will include the chemical, mechanical and physical properties of metals, mechanical behavior, microstructure and post-weld heat treating.

Prerequisites

(A requirement that must be completed before taking this course.)

Course Competencies

Upon successful completion of the course, the student should be able to:

• Examine the physical changes that occur to a metallic material upon rapid heating and cooling.
• Explore the effect of fusion welding processes on the microstructure of metallic weldments.
• Explore the effect of solid state welding processes on the microstructure of metallic weldments.
• Interpret changes in microstructure between the base metal and weld in metallic weldments.
• Identify the various types of weld discontinuities in metallic weldments.
• Explain how alloying elements in the base metal and filler metals affect the chemical, physical and mechanical properties of metallic weldments.
• Investigate methods of weld targeting to improve weld efficiency.
• Explore the effect of brazing on the microstructure of metallic brazements.
• Explore the nature of mechanical and thermally induced stresses on the behavior of metallic weldments.
