1. College-Wide Outcomes
College-Wide Outcomes/Competencies |
Students will be able to: |
Assess alternative solutions to a problem |
Evaluate methods available and select the best one for the project. |
Analyze and follow a sequence of operations |
Identify key components and order of events to properly weld with the GMAW process. |
Utilize appropriate technology |
Calculate the proper welding parameters when using a multi-process welders. |
2. Course Specific Outcomes - Students will be able to achieve the following measurable goals upon completion of
the course:
- Determine the proper shielding gas based on a material specific properties;
- Identify and implement changes to the proper work angle, proper travel angle, and proper travel speed based on a materials heat dissipating properties;
- Establish the proper weld sequencing to minimize discontinuities;
- Demonstrate an understanding of advanced welding machine parameters;
- Develop an understanding of weld discontinuities
- Select proper joint preparation required to complete structurally sound welds;
- Complete a variety of skill-welds in order to demonstrate an understanding of welding variables associated with base material types.
- Execute a variety of destructive weld tests in order to demonstrate an understanding of advanced welding skills, and weld certification practices; and
- Conclude through visual & destructive inspections if a weld is acceptable or rejected.
