Welding Fundamentals Practice Exam
Course Introduction
Welding Fundamentals provides an introduction to the basic principles and practices of welding, including the theory, methods, and safety considerations involved in joining metals. Students will explore various welding processes such as Shielded Metal Arc Welding (SMAW), Gas Metal Arc Welding (GMAW), and Gas Tungsten Arc Welding (GTAW), learning about their applications, advantages, and limitations. The course covers topics such as metal properties, joint design, electrode selection, and inspection techniques, while emphasizing proper setup and operation of welding equipment. Through a blend of classroom instruction and hands-on practice, students will develop foundational skills essential for further study or entry-level positions in welding and fabrication industries.
