Course Description

Develops knowledge and skills for welding and brazing common joints in all positions using the oxy-acetylene process. Prerequisites: Department permission required. Audit available.

Addendum to Course Description

This is an outcome based course utilizing a lecture/lab format.  This course includes classroom discussions, videos, and lab demonstrations of technical skills.  Course outcomes will include theoretical concepts, layout, fabrication, welding and safety.

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 lay out, prepare and assemble weld joints.
  • Understand and apply fundamentals of oxy-acetylene welding and brazing.
  • Weld and braze common joint assemblies with the oxy-acetylene process to AWS D1.1 Structural Steel Welding Code visual acceptance criteria in all positions.
  • Apply visual examination principles and practices in accordance with AWS D1.1

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 students 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

The student will be assessed on his/her ability to demonstrate the development of course outcomes. The methods of assessment may include one or more of the following: oral or written examinations, quizzes, written assignments, visual inspection, and welding tests.
