The following classif

    19、ications Class 1 (highest class) to Class 6 (lowest class) indicate the projects class(es) of weld joints.1.2.1 Class 1 Weld JointsThis covers complete penetration weld joints only. These weld joints apply where failure would cause a loss of the system and/or be hazardous to personnel. Class 1 weld

    20、joints are highly stressed (dynamic and cyclic loading) and characterized as a single point of failure with no redundancy for the redistribution of stress into another member.1.2.2 Class 2 Weld JointsThis covers both complete and partial penetration groove weld joints and fillet weld joints. These w

    21、eld joints apply where failure would reduce the overall efficiency of a system but loss of the system or a hazard to personnel would not be experienced.1.2.3 Class 3 Weld JointsThis covers both complete and partial penetration groove weld joints and fillet weld joints. These weld joints apply where

    22、failure would not affect the efficiency of a system nor create a hazard to personnel. Class 3 weld joints are connections of secondary members not subject to dynamic action and/or low stressed miscellaneous applications.1.2.4 Class 4 Weld JointsThis covers weld joints applicable to welding reinforci

    23、ng steel to primary structural members.1.2.5 Class 5 Weld JointsThis covers weld joints applicable to welding concrete reinforcing steel splices (prestressing steel excepted), steel connection devices, and inserts and anchors required in concrete construction.1.2.6 Class 6 Weld JointsThis covers plu

    24、g and slot weld joints as applicable to the requirements of the projects code(s).SECTION 05 05 23 Page 5Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-1.3 SYSTEM DESCRIPTION*NOTE: The drawings should be checked to ensure that any supplementary infor

    25、mation required by the paragraph has been shown and that there is no conflict between the drawings and the specifications. Complete information about location, type, size, and extent of all welds and nondestructive testing, where required, must be clearly shown on the drawings. When welding is to be

    26、 covered by more than one section in the contract specifications, this section covers all structural welding; the other sections cover the utilities or special equipment required inside the structure. Welding of utilities or special equipment to structural members must be done carefully so that the

    27、overall structure is not weakened. The extent of welding required must be clearly shown on drawings or covered by the contract specification. Revise this paragraph to clearly define the welding that is covered. Drawings or other section of the specifications must specify the strength of the base mat

    28、erial.Drawings or the text of the contract specifications must specify the weld requirements: tensile strength, elongation, shear strength, size, length, type, and location.*Conform the design of welded connections to AISC 360, unless otherwise indicated or specified. Material with welds will not be

    29、 accepted unless the welding is specified or indicated on the drawings or otherwise approved. Perform welding as specified in this section, except where additional requirements are shown on the drawings or are specified in other sections. Do not commence welding until welding procedures, inspectors,

    30、 nondestructive testing personnel, welders, welding operators, and tackers have been qualified and the submittals approved by the Contracting Officer. Perform all testing at or near the work site. Each Contractor performing welding shall maintain records of the test results obtained in welding proce

    31、dure, welder, welding operator, and tacker performance qualifications.1.3.1 Pre-erection Conference*NOTE: ASTM A 992 steel must be used for all buildings which have groove welds in their lateral force resisting systems, and are either in Seismic Design Categories D, E and F or in Category C and are

    32、Seismic Use Group III; this and the following paragraph will be retained for this type of buildings.Government personnel attending the pre-erection conference should include all field Quality Assurance (QA) inspectors, the building designer, the Engineer of Record (EOR) (if different from the SECTIO

    33、N 05 05 23 Page 6Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-designer) and the Project Manager (PM).*Hold a pre-erection conference prior to the start of the field welding, to bring all affected parties together and to gain a naturally clear unde

    34、rstanding of the project and the Welding Procedure Specifications (WPS) (which the Contractor shall develop and submit for all welding, including welding done using pre-qualified procedures). Mandatory attendance is required by all Contractors welding production and inspection personnel and appropri

    35、ate Government personnel. Include as items for discussion: responsibilities of various parties; welding procedures and processes to be followed; welding sequence (both within a joint and joint sequence within the building); inspection requirements and procedures, both visual and ultrasonic; welding

    36、schedule; fabrication of mock-up model; and other items deemed necessary by the attendees.1.3.2 Mock-up Model*NOTE: Building designer must designate, on the drawings, a joint to be used as a mock-up model. This model must represent a critical, but typical, field welded groove joint connection locate

    37、d at or near where a properly sequenced erection pattern starts.*Perform first the field-welded connection designated as the mock-up model on the drawings. All welders qualified and designated to perform field-welded groove joints must be present during the welding of the mock-up model connections a

    38、nd each one shall perform a part of the welding. Simulate with the mock-up test all physical and environmental conditions that will be encountered during the welding of all groove joints. Execute all inspection procedures required for groove welded joints, including NDE tests, on the mock-up model.

    39、All Contractor inspection and testing personnel designated to perform QC of groove welded joints must be present during the welding of the mock-up model and each one shall perform the inspection procedures to be performed on production welding of these joints. This mock-up model connection represent

    40、s the standard of performance, both for the welding and inspection procedures used and the results to be achieved in the production welding for these groove welded joints.1.4 SUBMITTALS*NOTE: Review submittal description (SD) definitions in Section 01 33 00 SUBMITTAL PROCEDURES and edit the followin

    41、g list to reflect only the submittals required for the project. Submittals should be kept to the minimum required for adequate quality control.A “G” following a submittal item indicates that the submittal requires Government approval. Some submittals are already marked with a “G”. Only delete an exi

    42、sting “G” if the submittal item is not complex and can be reviewed through the Contractors Quality Control system. Only add a “G” if the submittal is sufficiently important or complex in SECTION 05 05 23 Page 7Provided by IHSNot for ResaleNo reproduction or networking permitted without license from

    43、IHS-,-,-context of the project.For submittals requiring Government approval on Army projects, a code of up to three characters within the submittal tags may be used following the “G“ designation to indicate the approving authority. Codes for Army projects using the Resident Management System (RMS) a

    44、re: “AE“ for Architect-Engineer; “DO“ for District Office (Engineering Division or other organization in the District Office); “AO“ for Area Office; “RO“ for Resident Office; and “PO“ for Project Office. Codes following the “G“ typically are not used for Navy, Air Force, and NASA projects.Choose the first bracketed item for Navy, Air Force and NASA projects, or choose the second bracketed item for Army projects.*Government approval
