AWS Classification System

The AWS classification system provides means of identifying filler metals, fluxes, consumable inrts, and tungsten electrodes that meet the requirements of AWS specifications. Although a full explanation of the system and its symbols is beyond the scope of this document, the outline given below will provide a brief summary of the general scheme. For complete details, the pertinent specification should be consulted.

Prefix Letters

Prefix letters ud to indicate a product form, the joining process, or both are as follows:

E —	Indicates an arc welding electrode, which, by definition, carries the arc welding current.
R —	Indicates a welding rod which is heated by means other than by carrying the arc welding current.
ER —	Indicates a filler metal which may be ud either as an arc welding electrode or as a welding rod.
EC —	Indicates a composite electrode.
EW —	Indicates a (nonconsumable) tungsten electrode.
B —	Indicates a brazing filler metal.
RB —	Indicates a filler metal that may be ud as a welding rod or as a brazing filler metal, or both.
RG —	Indicates a welding rod to be ud in oxy-fuel gas welding.
F —	Indicates a flux for u in submerged arc welding.
IN —	Indicates a consumable inrt.

Symbols Following the Prefix

Classification symbols that follow the prefix are bad on criteria that best evaluate the welding capabilities of the filler metal for the applicable process. The criteria include (a) chemical composition of filler or weld metal, (b) weld metal mechanical properties, (c) certain process parameters or combinations of all factors or both. The classification system also varies with the major specification requirements.

Optional Supplemental Designators

R —	Moisture resistant electrode covering2
H16 —	Diffusible hydrogen shall be 16 ml/100g of weld metal maximum3
H8 —	Diffusible hydrogen shall be 8 ml/100 g of weld metal maximum2
H4 —	Diffusible hydrogen shall be 4 ml/100 g of weld metal maximum2
-1 —	Improved impact properties and somewhat higher ductility.
2 Only applies to electrodes found in AWS A5.1. 3 Prently, H16, H8, and H4 only apply to AWS A5.1 and A5.23.

Mild and Low Alloy Steel Covered Electrodes

For mild and low alloy steel covered electrodes, the prefix E is followed by a number ries which indicates minimum strength level, position capability, type of covering, and welding current. The following paragraph and table explains how the number ries is ud in AWS A5.1-81.

The letter E designates an electrode. The first two digits, 60, for example, designates tensile strength of at least 60 ksi for the weld metal, in the as-welded condition. The third digit indicates the position in which satisfactory welds can be made with the electrode. Thus, the "1" as in E6010, means that the electrode is satisfactory for u in all positions (flat, vertical, overhead, and horizontal). The "4" as in E7048, indicates the electrode is suitable for the flat position and also for vertical-down welding and for other positions (e table). The last two digits taken together indicate the type current with which the electrode can be ud and the type of covering on the electrode, as listed in the following table.

AWS Classification	Type of Covering	Capable of Producing Satisfactory Welds in Positions Shown a	Type of Current b
