STORAGE AND HANDLING OF CRITICAL WELD CONSUMABLES A fracture control plan is put in place to assure that projects containing fracture critical members (FCM) called out by the engineer of record are fabricated In accordance with the requirements of the Contract Documents as well as all steel bridge members and member components designated on the plans or elsewhere in the contract documents as “frac
MATERIAL PROCESS MANAGEMENT Now that you have a handle on your material stock, lets dive deeper into traceability and control.
Why do we need a fracture control plan? In order to fabricate most bridges in the United States of America especially for government contract work you will need a fracture control plan (FCP), So What is a fracture control plan and how do you implement one to maintain com
PAINT PROCESSES Prior to the start of any paint application you must verify that paint materials are in compliance with the specification and this includes checking packaging and labeling; verifying the condition of paint in the container; and taking samples for testing.
You should inspect the contents of all containers when opened for the first time or if reopened after an extended period of time
WELDING PROCESSES SMAW, FCAW and GMAW may be used to construct or repair FCMs, however most established bridge fabricators utilize mainly the SMAW, FCAW and SAW processes.
ESW and EGW are prohibited for welding FCMs. GMAW (exceptions allowed in 3.1) may only be used with the approval of the Engineer of Record , and when allowed, qualification tests, procedure control and NDT are normally specifi
BOLTING PROCESSES The ASTM F3125 Grade F1852, (Also known as A325 TC bolts) specification cover heat treated, steel, tension control bolt-nut-washer assemblies, also referred to as “sets.” Understand the A325 and A490 requirements of the Research Counsel of Structural Connections, per The American Institute of Steel Construction.
