Application
ER316H is used to weld wrought and cast forms of similar composition. The presence of molybdenum increases its creep resistance at elevated temperatures. The lower ferrite level of this nominal composition reduces the rate of corrosion in certain media and is suitable for use at cryogenic temperatures.

Application
ER316LSI affords the same characteristics as 316L. The high silicon allows better arc stability along with minimal post-weld grinding. The low carbon in the weld metal gives excellent assurance against intergranular corrosion.

WWZirconiated
Zirconium (ZrO2) = Contains small amount Zirconiated electrodes have welding characteristics that generally fall between those of pure and thoriated tungsten
Zirconiated electrodes are the tungsten electrode of choice for AC welding because of arc stability and starting characteristics of thoriated tungsten. EWZr-1 contains a small amount of Zirconium (Zr02) Has welding characteristics that generally fall between those of pure and thoriated tungsten
WW2% Thoriated
Thorium Oxide (ThO2) =2% called thoria
The thoria provides about 20 percent higher current-carrying capacity, longer life and resistance to contamination of the weld. Designed for DCEN applications, low level radioactive material. Note: If electrode grinding is used the dust might be ingested, special precautions relative to ventilation should always be considered.
WW2% Ceriated
Cerium Oxide (CeO2) = 2% referred to as ceria
Ceriated electrodes exhibit a reduced rate of vaporization or burn-off. EWCe-2 electrodes will operate successfully with AC welding.
WW1% Lanthanated
Lanthanum oxide (La2O3) = 1% referred to as Lanthana
Compared with pure tungsten, the lanthanum electrodes exhibit a reduced rate of vaporization or burn-off. Operate successfully with AC or DC
WW(Pure) Tungsten
Pure Tungsten (EWP) = minimum of 99.5 percent tungsten Contains no intentional alloying elements
Pure tungsten electrodes are used mainly with AC for welding aluminum and magnesium alloys. Can use DC, but does not provide arc initiation and arc stability as does the thoriated, ceriated, or lanthanated electrodes

Al = 2.5-3.5
V = 2.0-3.0

Y = 0.005 max
The reduced oxygen content of the ERTi-9ELI alloy results in slightly lower strength and improved toughness in comparison with weld metal from ERTi-9. Titanium is a reactive metal that is sensitive to embrittlement by oxygen, nitrogen and hydrogen at temperatures above 500F. This can be provided by shielding the metal with high purity inert gas or in a chamber. Cleanliness of the joint is a major factorin producing porosity free welds. Protection of the wire at all times is required to assure cleanliness. Can be fusion welded to Zirconium, Tantalum, Nobium and Vanadium. Should not be fusion welded to Copper, Iron, Nickel, and Aluminum, as it will produce extremely brittle welds

These materials are often referred to as “half 6-4” because the major components are roughly half that found in ERTi-5. Primary use, to date, has been in welding hydraulic tubing and fittings for aircraft. Has the ability to maintain strength at elevated temperatures.
