Examines the process of layout and fabrication of standard sheet metal fittings and how to construct standard fittings. Also covers sheet metal hand and power tools, and proper safety protocols.
Goals, Topics, and Objectives
This core class will be applied to Heating and Cooling/Power Engineering Basic Certificates, Advanced Certificates, or Associate Degree.
- Sheet Metal Careers.
- Sheet Metal Working Tools and Machinery.
- Sheet Metal Shop Safety.
- Sheet Metal Types.
- Materials of the Sheet Metal Trade.
- Fasteners for Sheet Metal.
- Patterns and Cutting Metal.
- Punching, Drilling, and Riveting.
- Folding Edges and Making Seams.
- Turning, Burring, and Raising.
- Forming, Crimping, Beading, and Grooving.
- Drawing and Notching Simple Patterns.
- Parallel Line Development.
- Demonstrate procedures for sheet metal layout.*
- Demonstrate by fabricating HVAC industry's most popular sheet metal fittings.
- Apply safety protocols related to the sheet metal craft, and apply them in the lab.
- Demonstrate the ability to use sheet metal hand tools.*
- Demonstrate the use of sheet metal power tools and forming machinery.
Students will learn how to prepare, layout, and then make paper patterns before making metal fittings. Esses and drives will be standard on all fittings.
Assessment and Requirements
Methods for measuring achievement of objectives:
- Layout: 25%
- Sheet metal laboratory activities and performance exercises will be done where students will demonstrate complete understanding of practical application of sheet metal fabrication. These will make up 25% of the course grade. Student "MUST" stay for lab, or absence will be recorded.
- Final-sheet metal exam: 25%
- Attendance is accounted for 25% of one's grade. Absence from class is part of not completing the required work, so each absence will result in a deduction of the final grade. This will only be explained once; if you cannot make it to class, you must make early arrangements with the instructor or call and leave a message on his phone or email.
