This specification establishes the requirements for classification of covered electrodes for underwater wet shielded metal arc welding. The requirements include mechanical properties of weld metal, weld metal soundness, and usability of electrode. Requirements for composition of the weld metal, standard sizes and lengths, marking, manufacturing, and packaging are also included. A guide to the use of the standard is included in an Annex.
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 â??manufacturerâ? 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 testing information shall be recorded as required by Figure 1. Water depth of welding shall also be 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.
