Course Description

Provides an opportunity to practice for the American Welding Society Mild Steel Welding Certification tests using SMAW low hydrogen electrodes in the vertical, horizontal and overhead positions. Audit available.

Addendum to Course Description

This is a outcome based course utilizing a lecture/lab format. This course includes classroom discussions, computer based instruction, and lab demonstrations. Course outcomes will include: theoretical concepts, layout, fabrication, welding, oxyfuel cutting, safety and environmental awareness, communication, computations and human relations.
 

Intended Outcomes for the course

Upon completion of the course students should be able to:

  • Function safely in the PCC Welding Lab.

  • Operate oxy-fuel portable and track cutting systems in accordance with industry standards.

  • Understand and apply code requirements for SMAW E7018.

  • Interpret blueprints to accurately lay out, prepare, and assemble weld joints.

  • Weld limited thickness single V-groove welds with E7018 to AWS D1.1 Structural Steel Welding Code.

  • Operate an CAC-A (Carbon Arc Cutting - Air) system in accordance with industry standards.

  • Apply visual and destructive 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 welding tests, safe work habits and task performance.
