Structural Steel Welding

Semih Genculu, P.E.

Course Outline

This two-hour course discusses the basic factors every engineer should know about structural steel welding. It is important to have an understanding of the potential problems and critical parameters that need to be taken into account in joining steels. This course will enable the designer to become familiar with the typical weld terminology, understand the metallurgical changes that occur during welding, and the precautions to take to avoid situations that can ultimately lead to failures.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.

Learning Objective

At the conclusion of this course, the student will:

• Become familiar with welding terms and symbols;
• Learn about the various arc welding processes and filler metal designations;
• Become aware of the significance of material composition and its effect on weldability;
• Recognize the type of defects that develop in welds;
• Understand the source of basic weld defects and remedies; and
• Develop a basic understanding of code requirements and contents of a welding procedure.

Course Introduction

There are numerous welding processes including arc welding, electron beam welding, friction welding, laser welding, and resistance welding. This course will concentrate on arc welding which is the most common technique used to join structural steels. The factors behind weldability will be discussed and how to avoid common weld defects will be presented.
