What you'll learn
- Describe the sheet metal trade, its main areas of work and the registered apprenticeship path to journeyworker, and keep an accurate logbook
- Apply workers' rights, the hierarchy of controls, machine guarding, lockout and personal protective equipment to the hazards of a sheet metal shop under OSHA's standards
- Calculate a daily noise dose from measured levels and exposure times, and choose controls and hearing protection accordingly
- Identify galvanized, galvannealed, aluminum, stainless steel, copper and other sheet materials, explain their coatings and properties, and prevent galvanic corrosion
- Read gauge and thickness specifications for different materials, measure sheet thickness accurately and calculate the weight of sheet and parts
- Use measuring and layout tools to establish reference lines, lay out square rectangles checked by diagonals, and calculate stretchouts on the mean diameter
- Select, use and maintain snips, seamers, hammers, stakes, punches and files, and estimate punching forces against tool capacities
- Use drills, drivers, shears, nibblers, grinders and saws safely, set drill speeds for the material and bit size, and manage batteries, cords and ground-fault protection
- Operate squaring shears, rotary and throatless shears, notchers and the ironworker safely within their rated capacities
- Bend sheet metal on cornice, bar folder, box and pan and press brakes, plan bending sequences, allow for springback and calculate bend allowances and developed lengths
- Roll cylinders on a slip roll and run roll-forming machines safely, and calculate round duct blanks with seam allowances and sheet yield
- Choose and apply screws, rivets, sealants, tapes and adhesives correctly, and plan, build, test and document a first shop project to a drawing
