Suggested Outcome Assessment Strategies

Written assessment requiring students to identify commonly used blueprint symbols, interpreting those symbols on drawings and understanding those symbols meanings.  Generated blueprints to be assessed based upon completeness and accuracy of measurement and annotation.  Produced parts from code (using CAD) will be assessed for accuracy of programming/code and accuracy of part produced.  Welded samples assessed to tolerance and accuracy from provided blueprints/drawings.

Course Activities and Design

The determination of teaching strategies used in the delivery of outcomes is generally left to the discretion of the instructor. Here are some strategies that you might consider when designing your course: lecture, small group/forum discussion, flipped classroom, dyads, oral presentation, role play, simulation scenarios, group projects, service learning projects, hands-on lab, peer review/workshops, cooperative learning (jigsaw, fishbowl), inquiry based instruction, differentiated instruction (learning centers), graphic organizers, etc.

Course Content

Outcome #1: Identify basic and intermediate blueprint annotation and markings.

• Learn basic weld symbols and annotations
• Understand direct application of welding symbols from sample blueprints
• Explain secondary annotations in welding blueprints and their use
• Show symbols as written, to as fitted, to as welded in diagrams

Outcome #2: Produce to tolerance welding samples from blueprints.

• Determine dimensions from blueprints
• Apply dimensions to fabrications create from blueprints  
• Understand tolerances taken from blueprints
• Weld sample projects from blueprints, accounting for tolerance and warp, and using correct weld type process, contour and position

Outcome #3: Create welding blueprints and drawings using computer aided design programs, such as SolidEdge 2D.

• Learn 2D cad functions in order to produce blueprints and proper welding annotations
• Utilize 2d CAD functions in order to produce part drawings for cutting with CNC plasma cutter
• Create welding blueprints in CAD programs with proper annotation and 3 view drawings.

Outcome #4: Understand programs and code used to create and produce parts in computer numerically controlled machine processes.

• Understand different g-code lines as they apply to CNC processes
• Utilize software to write code for cutting parts from drawings
• Determine offset and kerf within a driver program
• Optimize parts runs using nesting functionality

Outcome #5: Produce parts designs from computer aided design (CAD) programs and utilize CAD designs to create sample parts.

• Run code through a “driver” program to create physical parts from CAD drawings
• Recover failed operations by understanding g-code functions
• Ensure parts match in physical specification to as-drawn specification accounting for tolerance.

Department Notes

Safety glasses are required at all times in the welding lab, and are provided for students.  Students may also purchase their own safety glasses from a local supplier.  Long pants and closed toed shoes are required in the welding lab at all times.  Appropriate clothing must be worn to work in the lab (no synthetic materials, etc.).  Safety requirements are covered prior to work in the lab.
