AWS Classification

This is the American Welding Society (AWS) designation for the wire per AWS A5.10. "E" stands for "electrode." "R" indicates the wire can also be used as a filler rod for GTAW welding. The first digit indicates the electrode's primary alloying element (e.g., "4" for silicon). The second digit indicates if the electrode alloy has been strain hardened to increase its yield strength and tensile strength. (Higher digits indicate higher levels of strain hardening, and "0" indicates no strain hardening). The last two digits indicate the specific series for the electrode alloy.

Tensile Strength (Minimum Required)

This is the minimum required tensile strength for the alloy, as required by the AWS classification for the alloy. Tensile strength is the maximum stress, in kilopounds per square inch (ksi), a weld created with the alloy can withstand before it fractures.

Tensile Strength (As Welded)

This is the tensile strength of a weld deposit created with the alloy. Tensile strength is the maximum stress, in kilopounds per square inch (ksi), a material can withstand before it fractures, as given by the manufacture.

Yield Strength (Minimum Required)

This is the minimum required yield strength for the alloy, as required by the AWS classification for the alloy. Yield strength is the maximum stress, in kilopounds per square inch (ksi), a weld created with the alloy can withstand before it permanently deforms.

Compatible Shielding Gas

This indicates the type of shielding gas used with the alloy, which influences the characteristics of the welding arc, the penetration profile of the arc, and the weld bead appearance. The shielding gas also helps protect the weld pool from contaminants in the surrounding atmosphere.

100% Argon provides a stable arc, narrow penetration profile, consistent weld quality, and minimal spatter. It is the most commonly used shielding gas for TIG welding applications, and it is commonly used for welding nonferrous metals and for creating fillet and butt welds in MIG welding applications.
75% Argon/25% Helium produces more puddle fluidity and flatter beads than 100% argon shielding gas. It is recommended for use with axial spray transfer welding or pulsed spray transfer welding applications on aluminum, and it is recommended for short-circuit transfer welding applications on nickel alloys.
