It is an essential part of many industries, including construction, manufacturing, and repair. There are several different types of welding methods, each with its own advantages and disadvantages. In this educational material, we will cover the most commonly used and well-known welding methods in the world. The curriculum will include both theoretical and practical elements, with a focus on Shielded Metal Arc Welding (SMAW) and Gas Tungsten Arc Welding (GTAW). The material will also explain welding symbols on welding drawings and include quizzes and exams to reinforce learning.
