Introduction
Introduction (LSI Quadrant I):
In the industry of welding, there are many different types of materials and it is

important to know what type of metal you have to pick the best type of weld and
process.
Ask: “Can anyone tell me what metal, when tested with the grinding wheel, has a
red spark stream? (iron).” Discuss various answers. “Today we are going to
discuss ways in which you can identify metals.”
Begin the PowerPoint.
Outline
Outline (LSI Quadrant II):
Instructor Notes:
Introduction
The PowerPoint presentation
should be shown after the
introduction.
List the objectives on the board.
Show the PowerPoint.
I. Common ways to identify metals for welding:
i. File test
ii. Color coding
iii. Stamp (SAE/AISI number)
iv. Spark test.
II. SAE/AISI
i. SAE- Society of Automotive Engineers
ii. AISI- American Iron and Steel Institute
Show the students an
example of the SAE & AISI
designations.
III. Assign students a box of metals. Ask that
they identify them.
IV. Questions?
V. Guided practice.
VI. Independent practice.
VII. Review and check for mastery.
VIII. Informal assessment
IX. This may or may not be formally tested.
Students will use this skill throughout the
semester.

Guided Practice (LSI Quadrant III):
Students would select and identify various metals. They need to be able to
defend their decision to the other students and instructor.
Independent Practice (LSI Quadrant III):
1. Students, working in teams, can quiz each other on elements of metal identification
(students must be checked off on safety as well).
Summary
Review (LSI Quadrants I and IV):
Check for mastery/understanding by orally reviewing the students on the
information. Answer any questions the class may have. Ask individual students
identify the metals and what would be the best process for the metal properties.
Evaluation
Informal Assessment (LSI Quadrant III):
Instructor should monitor student understanding throughout the lesson. If further
explanation is needed on a given topic, instructor should elaborate or re-teach
that portion of the lesson. Check for general mastery level of each student during
review time.
Formal Assessment (LSI Quadrant III, IV):
There is no formal assessment at this time.
Extension/Enrichment (LSI Quadrant IV):
For those students who need remediation, a re-teach and review session will
reinforce the topics of concern. The remediation will need to be tailored to the
individual needs of the student.
