MIL-E-22200/10C

Abstract

This specification covers iron-powder, low-hydrogen types of covered electrodes for the fabrication and repair welding of low and medium carbon, high tensile, and higher-strength low-alloy steels for as-welded and stress-relieved application. <br>Iron-powder, low-hydrogen electrodes shall be furnished in the types, classes, and sizes shown in <a href="#FPJYDAAAAAAAAAAA-X4">table I</a>, as specified (see <a>6.2</a>). <strong>Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: Commander, SEA 03R42, Naval Sea Systems Command, 2531 Jefferson Davis Highway, Arlington, VA 22242-5160 by using the self-addressed Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter.</strong> <a name="FPJYDAAAAAAAAAAA-X4" id="FPJYDAAAAAAAAAAA-X4">TABLE I.

An electrode will be approved under one type classification and an electrode will not be approved if it differs in type from that stated in the manufacturer's request for test. The position description indicates the maximum size qualified under the specification. However, reference should be made to the Qualified Products List (QPL) for the selection of electrodes for all positions of welding. <u>2</u>/ The suffix RC added to the MIL type pertains to restriction of the copper content (see <a>3.5</a>). Requirements, tests, and acceptance criteria remain otherwise unchanged. <u>3</u>/ Electrodes of other sizes or for other positions may be tested for qualification subject to NAVSEA approval.</pre> <br> <br><b><u>Intended Use:</u></b> This specification is intended to cover several arc-welding steel electrodes of various alloys and strength levels that deposit weld metal that meets the mechanical property requirements given herein. These electrodes have an extremely low covering moisture content and should reduce the likelihood of underbead cracking in welding of such high yield strength steels as HY-80 and HY-100 of MIL-S-16216. This type is intended for general use in the welding of ordinary strength and high tensile steels such as grade DH-36 and grade EH-36T of MIL-S-22698 and for attachment of such steels to high yield strength steels such as HY-80 and HY-100. This type can be used for as-welded and stress-relieved applications. This electrode is intended for use with dc, reverse polarity electrical characteristics only. This type is intended for general use in the welding of HY-80, and HSLA-80 steels for as-welded and stress-relieved applications. This electrode is intended for use with dc, reverse polarity electrical characteristics only. This type is intended for general use in the welding of HY-100 and HSLA-100 steel for as-welded applications. This electrode is intended for use with dc, reverse polarity electrical characteristics only. This type is intended to cover electrodes for welding pressure and strength welds that will be subject to irradiation. <br>
