Intended Outcomes for the course

Upon completion of the course students should be able to:

  • Function safely in the PCC Welding Lab.
  • Interpret blueprints to accurately layout, prepare and assemble pipe joints to specified tolerances.
  • Demonstrate welding 2 inch schedule 80 mild steel pipe in the 5G and 6G positions to ASME Section IX Code quality standards.  
  • Apply visual examination principles and practices in accordance with ASME Section IX.

Course Activities and Design

Welding lec/lab courses are Open -Entry and Open Exit (OE/OE) and are offered concurrently. Courses are designed to meet the needs of the student with flexible scheduling options. Students may attend full time or part time. This is an OE/OE course which does not align with the normal academic calendar.

Outcome Assessment Strategies
