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)
Â
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)
Â
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.

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)
