Our welding department focuses on the fabrication of machine parts and the technology involved in electrical and gas welding. Our students receive practical welding training on sheet metal, MIG and TIG stainless steel, plasma cutting, cylinder rolling, and bending and cutting. Our program is designed to equip students with the key skills necessary to work for a wide range of businesses involved in the production of metal works, cutting (late, thread, stainless steel and gas), electrical and gas welding and the operation of machinery.
