Form:

This specification covers a low-alloy steel in the form of covered welding electrodes.

Application:

Primarily for use as filler metal for metal-arc welding of low-alloy steels when the deposited weld metal is required to have heat treating characteristics similar to those of the metals joined.

Classification:

The electrodes covered by this specification are classified as follows:

Type A - DC

Type B - DC-AC

When DC is specified, reverse polarity (electrode positive) is required.

If no type is specified, Type B shall be supplied.
