scope:

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.

Iron-powder, low-hydrogen electrodes shall be furnished in the types, classes, and sizes shown in table I, as specified (see 6.2). Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: Commander, Naval Sea Systems Command, SEA 3112, Department of the Navy, Washington, DC 20362 by using the self-addressed Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter.

intended Use:

This specification is intended to cover several low-hydrogen types of arc-welding electrodes of various alloys and strength levels, capable of depositing weld metal, that in the as-welded or stress-relieved conditions meet mechanical-property requirements given herein. It will be noted that, although these electrodes may be used for some applications in the as-welded condition, they are capable of stress relief as required. Properties may be affected by long time stress-relieving and slow cooling from stress-relieving temperature. Properties should be determined to be satisfactory after a simulated production postweld heat treatment by the user when requird by the fabrication document. The designation, low-hydrogen, is applied to electrodes having coverings that are substantially free of any compound that may liberate hydrogen in the arc. Low alloy steel electrodes that produce low-hydrogen in the arc have been found suitable for welding many steels that formerly gave serious difficulty through excessive porosity and underbead cracking, unless welded with high-alloy electrodes.

This type is intended to cover medium steel electrodes used in welding mild, medium or high-tensile steels such as grade HT of MIL-S-16113 and MIL-S-22698.

This type is intended to cover low-alloy electrodes capable of depositing weld metal of higher strength than type MIL-7018.

This type is intended to cover a special MIL-type electrode formulated to meet the long time (50-hours) stress-relieved mechanical-properties requirements only.

This type is intended to cover low-alloy electrodes suitable for welding steels having properties similar to those of the weld, and for welding attachments to HY-80 steel, as may be permitted. This electrode is intended to be used with the d.c., rp electrical characteristics only.

This type is intended to cover low-alloy electrodes for welding low-alloy, high-yield, notch-tough steel such as grade HY-80 of MIL-S-16216. This electrode is intended to be used with d.c., rp electrical characteristics only.

This type is intended to cover low-alloy electrodes for welding groove butt joints in HY-80 and T-1 steels. This electrode is intended to be used with d.c., rp electrical characteristics only.

This type is intended to cover electrodes for welding pressure and strength welds which will be subject to irradiation.
