This course on Fundamental of Welding Science and Technology aims to provide learners with a comprehensive understanding of welding processes and techniques. By the end of the course, students will be able to classify different types of welding and joints, interpret welding symbols, analyze welding power sources, understand the physics of welding including arc stability and metal transfer, and identify common welding defects. The course covers various welding methods such as oxy-fuel gas welding, shielded metal arc welding, gas tungsten arc welding, gas metal arc welding, and submerged arc welding. The teaching method includes lectures on theoretical concepts, practical demonstrations, and discussions on welding defects and inspection. This course is designed for individuals interested in pursuing a career in welding, engineering students, professionals in the manufacturing industry, or anyone looking to enhance their knowledge of welding science and technology.
