Welding In, On and Around Steel Joists

The welding of steel joists has taken many forms over the nearly 100-year history of the industry. Standardization has helped specifiers have confidence in the finished products used in thousands of projects every year. There remains a hangover of misunderstanding about how joists are welded, what aspects of American Welding Society (AWS) criteria apply and what the Engineer of Record should know about the welding of joists.

Learning Objectives:

• Identify key challenges and procedures related to welding in the manufacture of open web steel joists.
• Describe the welding processes and potential issues encountered during erection of open web steel joists.
• Differentiate between various welding types and methods used in the manufacturing of open web steel joists.
• Interpret the welding criteria outlined in the Steel Joist Institute SJI-100-2020 Specification and explain how it relates to AWS Specifications.
