What Do You Learn in Welding Class?

People have been welding for ages—it dates all the way back to the Middle Ages in fact, when blacksmiths would weld different iron tools by hammering them together. Over the years these methods have only increased in efficiency, with more automated methods invented in the last century for students to learn in welding class.
