IV. Learning Outcomes

1. College-Wide Outcomes

College-Wide Outcomes/Competencies	Students will be able to:
Analyze and follow a sequence of operations	Identify key components and order of events to properly weld with a stick electrode.
Apply abstract ideas to concrete situations	Apply welding principles to select the appropriate electrode for a given joint design.
Utilize appropriate technology	Calculate the proper welding parameters when using multi-process welders.

2. Course Specific Outcomes - Students will be able to achieve the following measurable goals upon completion of the course:

• Develop an understanding of weld discontinuities;
• Select proper joint preparation required to complete structurally sound welds;
• Create and follow a welding process sheet (WPS);
• Execute a die penetrant test;
• Perform destructive weld tests;
• Explain pipe weld positions and how they will affect welding parameters;
• Identify and implement the proper work angle, proper travel angle, proper weld placement given a WPS;
• Complete a variety of destructive weld tests in order to demonstrate an understanding of advanced welding skills, and weld certification practices; and
• Conclude through visual and destructive inspections if a weld is acceptable or rejected.
