1.1 This specification prescribes requirements for the classification, based on underwater wet welding test and associated evaluation, of covered electodes for underwater wet shielded metal arc welding. Requirements for certification of test results are also shown herein. The specfication covers frritic steel, austenitic stainless steel, and nickel fller 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).
