ELTR 2400 Metallurgy for Welders

Study of metal properties, phase transformations, and their impact on weld quality.

About this course

Welding is more than joining metal; it is a study of how materials react to intense heat. In ELTR 2400 Metallurgy for Welders, you will learn why metals behave the way they do when melted and cooled. You will explore the microscopic changes that happen inside metals, known as phase transformations, and see how these changes affect the strength and safety of a weld.

This course focuses on the practical side of metallurgy. You will not just memorise facts; you will use your knowledge to choose the right materials and techniques for specific jobs. By the end of the term, you will understand how to prevent common defects and ensure that welds last.

Who takes this course

This course is an elective for students in the Electrical & Mechanical Trades department. It is particularly useful for those pursuing the Welding & Fabrication Technician diploma or the Construction & Maintenance Electrician (Apprenticeship) program, as it provides essential background for high-quality fabrication and repair work.
