B. AWS D1.5 Bridge Welding Code. 1. Used only for those applications not governed by NYSSCM. a. Welding A852 steel . C. AASHTO Guide Specification for Highway Bridge Fabrication with . HPS70W Steel. 1. For welding HPS70W steel. II. Determine Weldability or Special Welding Concerns for the Base Metal. A. ASTM A7 (33 ksi min yield) 1. High Performance Steel Designers' Guidecracks before the bridge becomes unsafe. 2.4 Weldability A main thrust of the HPS Research Program is to develop bridge steels with significantly improved weldability [3]. Improving weldability reduces the high cost of fabrication associated high preheat temperatures, heat input control, post-weld treatment, and other stringent controls, Steel Bridge Fabrication Guide SpecificationSteel Bridge Collaboration S10.1, Steel Bridge Erection Guide Specification, which Owners are encouraged to adopt. In this document, imperatives are directed to the Contractor and Fabricator. Many references are made to the AASHTO/AWS D1.5M/D1.5 Bridge Welding Code. Specific section numbers are based on the 2015 edition, and subsequent editions COLORADO DEPARTMENT OF Mar 18, 2019 · Fabrication Inspection of Structural Steel Items for CDOT Road and Bridge 1.0 SCOPE 1.1 This plan provides a procedural guide for fabrication quality assurance inspection of structural steel items, for CDOT road and bridge projects. The purpose of this guide is to establish consistent and uniform inspection and Structural Steel Welding
