Module ID 04101 - Occupational Overview: The Sheet Metal Industry

The sheet metal craft plays an important role in

industry, with applications in HVACR, building

materials, transportation, manufacturing, architecture,

and countless consumer products. Sheet

metal craftworkers cut, bend, fold, shape, and connect

sheets of metal into the structures needed to

support all these applications, as well as many

others. This module provides an introduction to

the sheet metal craft and the diversity it offers. (7.5 hours)



Module ID 04102 - Sheet Metal Tools and Equipment

Sheet metal workers must complete a variety of

tasks using numerous hand tools, power tools,

and stationary equipment. Knowing which tool to

choose and how each is used are important skills

every craftworker must learn. Equally important

is the knowledge of safety and maintenance

requirements for each tool. To become a successful

craftworker, regardless of the craft, a sheet metal

worker must know the tools available and how to

safely apply them to the task at hand. (10 hours)


Module ID 29103 - Plasma Arc Cutting

Welders must be familiar with the task of plasma

arc cutting. This module presents information

related to the plasma arc cutting process, including

safety procedures, setup, gas types, flow rates,

and equipment. (7.5 hours)


Module ID 04104 - Sheet Metal Math and Measurements

Math skills are especially important in the sheet

metal craft. Laying out, creating, and assembling

the many unique workpieces needed requires good

math skills. Good math skills are one of several characteristics

that identify sheet metal craft professionals

and separate them from others. The best way to

advance and hone those skills is through practice. (20 hours)


Module ID 04103 - Sheet Metal Layout and Processes

Before sheet metal craftworkers can safely and

effectively perform all the tasks needed to transform

sheets of metal into the array of shapes used in

construction, a fundamental understanding of basic

sheet metal layout and forming processes must be

developed. This module explains some of the general

rules that apply to sheet metal layout work, and

it describes how to select and use some common

layout tools. It also explains the three primary methods

used for laying out sheet metal patterns, and

describes how to cut, form, and assemble finished

objects. (17.5 hours)


Module ID 04105 - Parallel Line Development

Of the three methods used for sheet metal layout,

parallel line development is the one most frequently

used to create sheet metal fittings for air distribution

systems. This module examines how to use

parallel line development to lay out the patterns to

fabricate various fittings commonly used in HVAC

systems. Developing layout and fabrication skills is

very important to any sheet metal craftworker. If a

pattern is laid out incorrectly, the fitting that results

will not fit together with other components in the

system, and rework becomes necessary. (27.5 hours)


Module ID 04106 - Installation of Ductwork

To install ductwork, craftworkers must be able to

identify and select fasteners, hangers, and supports

for the installation of duct and other HVAC

system components. To do so, it is important to

understand load requirements and the standards

related to hangers and supports. The module also

presents information regarding the reduction

of noise created by air distribution equipment.

(15 hours)


Module ID 04107 - Installation of Air Distribution Accessories

Each accessory in an air distribution system performs

a specific task. The goal may be to control

air volume in various ducts, provide service access

for components inside the duct, or safeguard

against fire and smoke distribution in the event

of a fire. A variety of accessories like these and

others are presented in this module, along with

their unique installation considerations. (12.5 hours)
