11-2.05 WELDING INSPECTIONReplace clause 6.5.4 of AWS D1.5 with: The QC Inspector must inspect and approve each joint preparation, assembly practice, welding technique, joint fit-up, and the performance of each welder, welding operator, and tack welder to make certain that the applicable requirements of this code and the qualified WPS are met. The QC Inspector must examine the work to make certain that it complies with clauses 3 and 6.26. The size and contour of all welds must be measured using suitable gauges. Visual inspection for cracks in welds and base metal, and for other discontinuities must be aided by strong light, magnifiers, or other devices as necessary. You may use acceptance criteria different from those specified in this code if authorized. 11-2.06 WELDING PROCEDURES QUALIFICATIONWelding procedures qualification for work welded under AWS D1.5 must comply with clause 5.12 or 5.12.4 of AWS D1.5 and the following: 1. Unless considered prequalified, qualify fillet welds in each position. Conduct the fillet weld soundness test using the essential variables of the WPS as established by the PQR. 2. For qualifying joints that do not comply with figures 2.4 and 2.5 of AWS D1.5, conduct the test complying with figure 5.3 using the welding parameters that were established for the test conducted complying with figure 5.1. 3. Macroetch tests are required for WPS qualification tests, and acceptance must comply with clause 5.19.3 of AWS D1.5. 4. If a nonstandard weld joint is to be made using a combination of WPSs, you may conduct a test under figure 5.3, combining the qualified or prequalified WPSs to be used in production, if the essential variables, including weld bead placement, of each process are limited to those established in table 5.3 of AWS D1.5. 5. Before preparing mechanical test specimens, inspect the PQR welds by visual and radiographic tests. The backing bar must be 3 inches in width and must remain in place during NDT. Results of the visual and radiographic tests must comply with clause 6.26.2 of AWS D1.5 excluding clause 6.26.2.2. All other requirements for clause 5.17 are applicable. 11-2.07 REPAIR WORKNotify the Engineer immediately if you discover welding problems, deficiencies, base metal repairs, or any other type of repairs not included in the welding QC plan. Submit the proposed repair procedures to correct them. Allow the Engineer 7 days to review the repair procedures. You must receive authorization before performing: 1. 3rd-time excavations of welds or base metal to repair unacceptable discontinuities, regardless of NDT method 3. Repairs not included in the welding QC plan Requests to perform 3rd-time excavations, repairs of cracks, or repairs not included in the welding QC plan must include an engineering evaluation. At a minimum, the engineering evaluation must address: 1. Cause of each defect 2. Why the repair will not degrade the material properties 3. What steps are being taken to prevent similar defects from happening again 11-3 WELDING FOR OVERHEAD SIGN STRUCTURES, STANDARDS, AND POLES 11-3.01 GENERALSection 11-3 applies to work welded under sections 56-2 and 56-3.02. Fabricate overhead sign structures, standards, and poles at a plant on the Authorized Facility Audit List. 11-3.02 WELDING INSPECTIONWelding inspection personnel or NDT firms to be used in the work must not be employed or compensated by any subcontractor or by other persons or entities hired by subcontractors who provide other services or materials for the Contract except for welding performed at a permanent fabrication or manufacturing plant that is certified under the AISC Quality Certification Program. The AISC Certification category for overhead sign structures is Bridge and Highway Metal Component (CPT) or Simple Steel Bridge Structures (SBR). The AISC Certification category for pole structures is Bridge and Highway Metal Component (CPT) or Standard for Steel Building Structures (STD).
11-3.03 SUBMITTALSSubmit a welding report under section 11-2.03C except submit the welding report 2 business days before submitting the certificate of compliance. 11-4–11-9 RESERVED 12 TEMPORARY TRAFFIC CONTROL 12-1 GENERAL 12-1.01 GENERALSection 12-1 includes general specifications for providing temporary traffic control. Temporary traffic control, including flagging, apparel, temporary traffic control devices, and equipment for flaggers, must comply with the California MUTCD, Part 6, "Temporary Traffic Control." 12-1.02 MATERIALSNot Used 12-1.03 CONSTRUCTIONAssign flaggers to: 2.
