The Welding Technology program utilizes the books and videos from the Hobart Institute of Welding Technology, as well as lecture and live demonstrations from a qualified instructor. The Welding Technology program provides students with the necessary skills and knowledge to enter an apprenticeship program or be qualified as an entry level welder in most industries. Students are instructed on different methods of welding including; SMAW, GMAW, FCAW, and GTAW. Students also study welding symbols and blueprint reading. Students perform related tasks such as cutting, grinding, machine operation, and basic fabrication according to layouts, and blueprints. Students work in teams on private and school or community projects. These projects vary from new construction to rebuilding and/ or repairing existing projects // (Vocational Curriculum standard #4.3). // Proper safety procedures are emphasized with the use of all equipment. Students mastering all the assigned duties have the opportunity to earn, a national AWS welding certification in SMAW, FCAW, and GTAW. // (Vocational Curriculum standard #4.4) // // (Vocational Curriculum standard #4.5). // The welding technology program participates in Skills USA and AWS (American Welding Society) // (Vocational Curriculum standard #4.9). // Members develop technical and leadership skills by interacting with industry professionals, welding students and instructors from other schools. At the end of the program students receive a portfolio with their resumes, outstanding achievement awards and documentation of each of the practical welding tasks they successfully completed. // (Vocational Curriculum standard #4.7) //
