Your options for welding classes depend on where you live and whether you’re willing to travel. Many skilled professionals offer private or group welding classes across the U.S. Some high schools offer classes for teens, but many people learn from a private trainer or in a junior college or vocational school. Students learn basic welding, machining and fabrication processes, including using gas and arc welding equipment, and qualify for an apprenticeship or internship. Other colleges as well as vocational schools have two-year associate’s degree programs that prepare you to take the welding certification exam and seek full-time employment.
