Southern MN Area Sheet Metal Training


In spite of technological changes, the Sheet Metal Worker remains nearly the only building tradesperson to start with raw materials, custom-make complex systems, and then install them. He/she can transform flat sheets of metal into any size or shape that is required by working from a blueprint or verbal instructions.

Being a Sheet Metal Worker involves the fabrication, erection, installation, repairing, replacing and servicing of all residential heating and air conditioning systems and the architectural sheet metal work on such residences.

Workers will gain a knowledge of heating, cooling and ventilation systems, techniques of welding, and the functions of compressors and condensers in the refrigeration cycle. Includes areas such as solar installation, hoisting and rigging, soldering, and energy management and retrofitting of environmental systems. Most people consider the term "air conditioning" to merely imply cooling the air. But air conditioning is much more comprehensive when the term "conditioning the air" is used.

Sheet Metal Workers help provide these types of systems; which heat, cool, and ventilate - providing a completely controlled environment. The rapidly expanding use of new materials and processes in manufacturing plants throughout the nation today is presenting new health hazards at an alarming rate. The Sheet Metal Workers also helps provide systems that will safely remove fumes, dust, smoke, heat, odors, carbon dioxide and other dangerous contaminants to combat this situation.

Many Sheet Metal Workers also have an important role due to the large amount of sheet metal work that goes into sign making, hospital and restaurant equipment, aircraft and shipbuilding, In addition, the knowledge and skill of the Sheet Metal Worker is needed by other industries in products requiring sheet metal work.
