Metallurgy for Welders Exam
Questions
Course Introduction
Metallurgy for Welders provides an essential overview of how metals behave during the welding process, focusing on the structures, properties, and transformations that occur due to heat and mechanical manipulation. The course covers fundamental concepts such as the iron-carbon phase diagram, crystalline structures, heat-affected zones, and the effects of alloying elements. Students will explore common welding metals, the impact of cooling rates, metallurgical defects, and how to select appropriate materials and processes to maximize weld quality and performance. Emphasis is placed on practical applications, case studies, and the interpretation of microstructures to develop a strong foundational knowledge that enables welders to make informed decisions in real-world fabrication and repair scenarios.
