Course Description

Covers the language of blueprints including lines, views, dimensioning, print organization, welding symbols and structural shapes. Prerequisites: WR 115, RD 115 and MTH 20 or equivalent placement test scores. Audit available.

Addendum to Course Description

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. 

Intended Outcomes for the course

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. Understand the specifications and edge preparation 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).

Outcome Assessment Strategies

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.
