Form:

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

Application:

This wire has been used typically as filler metal for gas-tungsten-arc and gas-metal-arc welding of low-alloy steels of similar composition where the weld area is required to have strength and notch-toughness comparable to that of the parent metal without the need for post-weld heat treatment, but usage is not limited to such applications.

Classification:

Wire shall be classified as follows:

Type 1 - Bare Wire

Type 2 - Copper Coated Type 1 shall be supplied unless Type 2 is specified.
