Apprentices will begin using pattern templates to layout, cut and weld various fabricated projects. They will begin the complex build of a modular mechanical system. They will continue learning about various materials and tools used to bend tube piping. They will be introduced to specialty welding techniques, such as back feeding, heavy wall pipe, large diameter downhill, and lay wire welds. Finally, they will be introduced to the international mechanical code, which provides the guidance needed to interpret city of Seattle refrigeration regulations, thus earning the city's license for this work.
