欧洲杯决赛竞猜app_欧洲杯足球网-投注|官网s knowledge and skills required to weld common joints in all positions on stainless steel using the gas tungsten arc welding (GTAW) process. Audit available.

Addendum to Course Description

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

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  weld joints.
  • Understand and apply fundamentals of GTAW operations.
  • Weld common joints using gas tungsten arc welding 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 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

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 , welding tests and task performance.
