Course Standards
Safety
1) Accurately read, interpret, and demonstrate adherence to safety rules, including rules published
by the (1) National Science Teachers Association (NSTA), (2) rules pertaining to electrical safety,
(3) Occupational Safety and Health Administration (OSHA) guidelines, (4) American Society for
Testing Materials; ANSI Z49.1: Safety and Welding, Cutting, and Allied Processes, and (5) state
and national code requirements. Be able to distinguish between rules and explain why certain
rules apply. Complete safety test with 100 percent accuracy.
2) Identify and explain the intended use of safety equipment available in the classroom. For
example, demonstrate how to properly inspect, use, store, and maintain safe operating
procedures with tools and equipment.
Career Exploration
3) Locate and assess the American Welding Society website and analyze its structure, policies, and
requirements for the AWS Entry Welder qualification and certification. Explain a welder
certification document, what steps are required to obtain the certification, and how to prepare
for the examination.
Interpreting and Creating Drawings
4) Compare and contrast the architectural scale versus the engineering scale used in mechanical
drawings. Describe their distinguishing characteristics. Define a scale and perform conversion
calculations of various distances.
5) Building on the knowledge of a two-dimensional drawing, create simple isometric (3-D pictorial)
drawings, properly using lines (e.g., object, hidden, center), labels, and dimensioning
techniques.
Welding Design and Layout
6) Identify, sketch, and explain the five basic weld joint designs (e.g., butt, lap, tee, outside corner,
and edge). Find examples of various joint designs applied to structures on or around campus and
take pictures to present to classmates.
7) Demonstrate proper laying out of parts for fabrication by marking lines and locating points for
cutting, bending, drilling, and assembling. Identify the factors that influence effective layout and
explain how to maximize the desired outcome. For example, plan the placement of parts
together so as to minimize the waste of stock material.
Shielded Metal Arc Welding (SMAW)
8) Safely set up equipment for shielded metal arc welding (SMAW). Identify and explain the
equipment, equipment setup, and the electrical current used in the welding process. Drawing on
multiple resources, compare and contrast SMAW with other welding and cutting processes such
as oxyfuel gas welding (OFW), gas metal arc welding (GMAW), flux-cored arc welding (FCAW),
and gas tungsten arc welding (GTAW). Write a brief informative paper discussing the
distinguishing characteristics and primary advantages of each.
9) Demonstrate how to make single- and multiple-pass fillet welds and groove welds with backing
on plain carbon steel in the following positions. Prior to welding, sketch a cross section,
including the dimensions of each weld demonstration.
a. Flat
b. Horizontal
c. Vertical
d. Overhead
10) Research the American Welding Society (AWS) filler metal classification system and write a
paper explaining the system, briefly discussing the multiple factors that affect electrode
selection for shielded metal arc welding (SMAW). Using various electrodes, demonstrate how to
make pad beads on plain carbon steel in the following positions.
a. Flat
b. Horizontal
c. Vertical
d. Overhead
Summarize the demonstration results of using various electrodes and explain the findings using
supporting evidence from the AWS metal classification system.
Properties of Metals
11) Research the following mechanical properties of metals and their importance in the welding
process.
a. Tensile
b. Strength
c. Hardness
d. Elasticity
e. Ductility
f. Toughness
g. Brittleness
Create a chart or table that compares and contrasts the meaning of these properties. Explain
the changes in the mechanical properties of weldments that occur during the welding process.
12) Investigate the thermal properties of metals and their effects on welding processes. Describe
and demonstrate techniques to mitigate the effects of thermal expansion and contraction that
occur during the welding process. During the demonstrations, observe and record the changes
that occur in the mechanical properties of weld and parent metals caused by heating and
cooling. Write a report summarizing and explaining the findings. Justify all explanations with
supporting evidence gathered from observations and welding principles.
13) Design an experiment to test and compare the effect that thermal conductivity and specific heat
have on various metals such as steel and aluminum. Record all observations and write a report
to present the test results in an electronic format, integrating quantitative and visual
information. The report should include, but should not be limited to, explaining the effect of
thermal conductivity on the heating and cooling rates observed during the welding process, as
well as the effect of specific heat on heat rates required for welding.
Quality Control
14) Drawing upon multiple resources, research and write a text explaining the relationship between
discontinuities and defects. Describe various examples of defects found in welded products. Also
identify and explain both destructive and nondestructive tests used as quality control
techniques to prevent manufacturing defects in welding. Compare and contrast these
techniques and provide specific examples when they are most appropriately used. Cite evidence
to justify the examples.
15) Measure and visually inspect welded products for acceptability to American Welding Society QC-
10 standards. Record discontinuities and defects, and compare data to given project
specifications using class-defined analysis methods. Interpret and communicate results both
written and verbally. If necessary, recommend changes that will reduce the number of product
defects during the manufacturing process.
