4. Acceptance Acceptance of welding electrodes (those to which an auxiliary waterproof coating is to be applied) shall be in accordance with the provisions of AWS A5.01M/A5.01 (ISO 14344 MOD) or equivalent document. Additional procurement requirements for wet welding electrodes are covered in this specification.
5. Certification By affixing the AWS specification and classification designations to the packaging, or the classification to the product, the manufacturer certifies that the product meets the requirements of this specification.
6. Rounding Procedure For purposes of determining compliance with the requirements of this specification, the actual test values obtained shall be subjected to the rounding rules of ASTM E29 or ISO 80000-1, Annex B, Rule A (the results are the same). If the measured values are obtained by equipment calibrated in units other than (hose of the speci tied limit, the measured values shall be converted to the units of the specified limit before rounding. If an average value is to he compared to the specified limit. rounding shall be done only after calculating the average. An observed or calculated value shall be rounded to the nearest lXX psi for tensile and yield strength for AWS A5.35 (U.S. Customary Unit standard) and to the nearest 10 MPa for tensile and yield strength for AWS A5.35M (SI unit standard): and to the nearest unit in the last right-hand place of figures used in expressing the limiting values for other quantities. The rounded results shall fulfill the requirements for the classification under test.
7. Auxiliary Coating Integrity
Auxiliary coatings shall be uniform with no breaks or flaking which would degrade electrode performance. The auxiliary coatings shall be applied so as to provide complete coverage of the electrode. They shall extend from at least 1/16 in 11.5 mriij beyond the covering on the grip end and shall completely seal the arc end. The auxiliary coatings shall not interfere with electrical continuity between the electrode and the electrode holder.
8. Summary of Tests
8.1 Testing. Testing for conformance to this specification shall be as required by Tables 4 and 5. This testing represents only the electrode chemical composition and diameter, method of manufacture, and auxiliary coating system tested. Any changes to the electrode chemical composition or diameter, method of manufacture (including electrode core wire and flux formulation), formulation of auxiliary coatings. or any addition or deletion of an auxiliary coating, shall require retesting for conformance to the specification: the modified electrodes shall be identified using a different or modified designation from the original.
All test assemblies shall be tested in the as-welded condition; no form of heating shall be used on any test assembly after welding. Grinding is not permitted on the weld reinforcement except for the purpose of magnetic particle testing (MT) or liquid penetrant testing (PT). and only after the weld has passed visual testing (VT).
All welding and testing is to be witnessed, and results certified, by an independent third party AWS Certified Welding Inspector with at least five years of experience associated with underwater wet welding projects, or an individual with equivalent qualifications and experience.
The information required by Figure 1, and the results of all testing, shall be certified by the manufacturer and the independent third party inspector, and maintained on tile by the manufacturer for review by potential users of the wet welding electrodes.AWS A5.35／A5.35M pdf download.
