Suggested Outcome Assessment Strategies

Outcomes are assessed through a mixture of hands on and written assessments.  Priority is given to hands-on proficiency-based assessment in an environment that rewards demonstration of skill needed for success in industry.

• Lecture and in-booth coaching and direct instruction.
• Direct instruction in full class demonstration of skills.
• Written exams.
• Student proficiency through demonstration of learned strategies and skills in industry standard environment.
• Mock AWS Testing procedure (destructive testing) or mock local industry supported on-site testing procedures.
• Job readiness based on performance.
• In class lab experiments and testing using the scientific process with written result reporting.

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: Create Solid Modeling in 3d CAD software.

• Understand different tools and concepts used in industry used 3D modeling software.
• Use basic functions to create work within solid modeling software.
• Utilize tools within 3D CAD software to recreate a solid model from a physical part.

Outcome #2: Utilize extrusion, fillets and chamfers to generate drawings.

• Create more complex models using extrusion techniques and fillets and chamfers.
• Generate a completed product drawing including dimensions and fastener holes.
• Simulate machine tool pathing to ensure design is production ready.

Outcome #3: Understand machining tolerances as they apply to 3d models for manufacturing using machining equipment.

• Apply tolerance and GD&T to a solid model.
• Understand different types of tooling for machining and it’s limitations and tolerances as they apply to a solid model.
• Utilize the simulator to verify accuracy of expected GD&T, and veracity of modeling.

Outcome #4: Create product from a solid 3d model.

• Generate a blueprint with 3rd dimensional orthographic projection.
• Create a solid model and simulate production processes in the simulator.
• Fabricate from the solid model to physical product.

Suggested Texts and Materials

Resources are available openly on the web, but largely the curriculum adaptation needs to be done based on the instructors existing skill set.  Since there are many ways to teach the content, the “teach what you know, and teach well what you do” is very appropriate for courses like this.

Suggested/recommended text:

• Print Reading for Welders 5th Edition Thomas E. Proctor, Jonathan F. Gosse

Suggested Resources:

• AWS Structural Code Book 2020
• Aeorspacewelding.com
• Thefabricator.com
• Aws.org

• Amatrol Learning Systems Curriculum

Students utilize on campus computer resources and software, e.g. CAD resources.

Department Notes

Safety glasses are required at all times in the manufacturing 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, ect.). Safety requirements are covered prior to work in the lab.
