MIL-E-23765/2E

Abstract

This specification covers low alloy steel solid bare welding electrodes for use with the gas metal arc welding (GMAW) process and the submerged arc welding (SAW) process employing a neutral granular flux, low alloy steel alloy cored bare welding electrodes for use with the GMAW process and the SAW process employing a neutral granular flux, and low alloy steel solid bare electrodes and cut length rods for use with the gas tungsten arc welding (GTAW) process. <b><u>Intended Use:</u></b> This specification is intended to cover low alloy steel solid bare welding electrodes and rods and alloy cored bare welding electrodes for depositing weld metal, that, in the as-welded condition, meets the mechanical properties specified herein when welded on the applicable base metals as specified in <a>table X</a> using GMAW, GTAW, and SAW processes. This specification also is intended to cover low alloy steel solid bare welding electrodes and rods for depositing weld metal, that in the stress-relieved condition meets the mechanical properties specified herein when welded on the applicable base metals as specified in <a>table X</a> using either SAW welding processes employing a suitable neutral granular flux or GMAW and GTAW processes with a suitable shielding gas. Types MIL-100S-1, MIL-100S-2, MIL-120S-1 and MIL-120S-2 or MIL-100S-1F, MIL-100S-2F, MIL-120S-1F and MIL-120S-2F, are intended only for as-welded applications. If they are conformance tested in the stress-relief condition and bear the SR suffix, they may be used for stress-relief applications as well. Type MIL-80S-1 and MIL-80S-2 electrodes are suitable for welding MIL-S-23194, composition A steels; MIL-S-24238, composition A steels; ASTM A 508, class 2 or 3 steels; and ASTM A 533 or ASTM A 302 steels using the SAW process. Type MIL-80S-3 is suitable for welding the same steels using the GMAW and GTAW processes. Type MIL-100S-1 electrode is suitable for welding HY-80 steel. Type MIL-100S-2 electrode is suitable for welding HY-80 steel, especially for approved reduced preheat applications. Type MIL-120S-1 electrode is suitable for welding HY-100 steel. Type MIL-120S-2 electrode is suitable for welding HY-100 steel. MIL-100S-1F, MIL-100S-2F, MIL-120S-1F and MIL-120S-2F are the designations of neutral granular flux to be used with the corresponding type of electrode. Restricted copper electrodes and rods will be used when specified (see <a>6.2</a> and <a>table I</a>). MIL-120S-1X and MIL-120S-2X electrodes are suitable for welding HY-100 steel with the SAW process using ac current only. Alloy cored electrodes are intended for use with the GMAW and SAW processes only. MIL-100S and MIL-120S types with higher carbon content are intended for use with SAW only. For MIL-120S type electrodes with the SAW process and all alloy cored electrodes with the SAW process, only those electrode and flux combinations approved are listed on the QPL. <br>
