1. Scope
1.1 This specification prescribes requirements for the classification, based on underwater wet welding test and associated evaluation, of covered electrodes for underwater wet shielded metal arc welding. Requirements for certification of test results are also shown herein. The specification covers ferritic steel, austenitic stainless steel, and nickel filler metals plus any auxiliary coatings applied over the electrode covering. Unless otherwise specified herein, the term“manufacturer'refers to the provider of the finished product (the electrode ready for underwater use). The requirements herein are intended to classify electrodes without consideration for potential base metals to be welded; suitability for specific base metals should be established by the customer during welding procedure qualification testing (see Annex A for further considerations).
This specification does not govern depth of water capability or maximum exposure time for wet welding electrodes classified to this document. However, such information shall be clearly shown as required by the marking requirements of : Clause 14.: Safety and health issues and concerns are beyond the scope of this standard and, therefore, are not fully addressed herein.Some safety and health information can be found in informative Annex A. Safety and health information is available from other sources, including, but not limited to, ANSI Z49.1, Safety in Welding, Cutting, and Allied Processes, and applicable federal and state regulations.
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.
8.2 Evaluation. Evaluation of inspection and test results shall be in accordance with Table 6. Three levels of quality, or integrity, are identified (Table 2) as applied in Table 6; Level 1 is the highest quality, while Level 3 is the lowest quality. The electrode classification (see Table 2) will reflect a particular electrode's capability in meeting the quality level indicated. The criteria in Table 6 will aid the customer in selecting the quality level of electrode desired for a specific application.AWS A5.35-A5.35M pdf download.
