Portland Community College | Portland, Oregon

This is an outcome based course utilizing a lecture format.  This course includes classroom discussions and practical demonstrations.  Course outcomes will include the following: the ability to follow detailed verbal and written instructions, develop visualization and interpretation skills and understand and perform lay out. 

Upon completion of the course students should be able to:

1. Evaluate the basic elements of a blueprint.
2. Create orthographic, oblique and isometric drawings by visualizing three dimensional objects.
3. Demonstrate an understanding of the AWS Welding Symbol and its location of elements.
4. Identify edge preparations and specifications for common weld types.
5. Demonstrate a basic understanding of metallurgy.
6. Identify common structural steel shapes and threaded and non-threaded fasteners.
7. Demonstrate a basic understanding of non-destructive examination (NDE).

Assessment is a continuous process throughout the learning experience.  The student will be involved in a self-assessment, peer assessment and instructor assessment of performance tasks and course outcomes.  The course syllabus will identify the criteria for assigning a course grade.  The methods of assessment will include one or more of the following: oral or written examinations, quizzes, and written assignments.

Evaluate the basic elements of a blueprint.

• Assess notes, views, lines, sections and detail drawings
• Interpret weld symbols, tolerances and dimensioning

Create orthographic, oblique and isometric drawings by visualizing three dimensional objects

• Utilize orthographic projections to develop a sketch of missing views

Understand the specifications and edge preparation for common weld types

• Interpret edge prep and specifications for the following weld types: fillet, groove, back, backing, melt-through, plug, slot, surfacing, edge, spot, seam, stud-                         weld, surfacing, and pipe-welding

Demonstrate a basic understanding of metallurgy

• Explain metal structure
• Classify ferrous and nonferrous metals
