Course Description

Develops technical knowledge necessary for the reading and understanding of the AWS Structural Steel Welding Code, D1.1. Enables the use of a systematic method in the application and understanding of the Structural Steel Welding Code. Prerequisites: MTH 20. Prerequisites/concurrent: (WR 90 or IRW 90) and (RD 115 or IRW 115). Audit available.

Addendum to Course Description

This is an outcome-based course utilizing a lecture format. This course is comprised of an introductory module and five (5) additional modules. Each of the modules, AWS D1.1, Section 1- General Provisions, Section 2 - Design of Welded Connections, Section 3 - Prequalification of Weld Procedure Specification (WPS), Section 4 - Qualification, and Section 5 - Fabrication, covers a specific section, or group of sections, of the Code. The questions following each module illustrate the type of 'question' likely to be encountered in practice.

Intended Outcomes for the course

Upon completion of the course students should be able to:

  • Demonstrate professional work ethics.
  • Develop a Welding Procedure Qualification Record (PQR), Welding Procedure Specification Record (WPS), and Welder Qualification Record.
  • Complete Weld Procedure Specification (WPS) documents in accordance with AWS D1.1.
  • Demonstrate the ability to read, understand, and apply the provisions of AWS D1.1.

Outcome Assessment Strategies

The student will be assessed on his/her ability to demonstrate the achievement of course outcomes. The methods of assessment will include one or more of the following: oral or written examinations, written assignments, work habits, task performance and work relations.
