Application
ER309 is used for the welding of similar alloys in wrought or cast form. It is mostly used for welding dissimilar materials such as mild steel to stainless steel, as well as for a barrier layer in stainless overlays. For some applications, welding of straight chromium steels can be accomplished with this consumable.

Deposited All Weld Metal Properties
Data is typical for ER309 weld metal deposited by Tig using 100% Argon as the shielding gas.

Recommended Welding Parameters
GTAW “Tig Process”
Wire Diameter Amps DCSP Volts Shielding Gas
.035 60-90 12-15 Argon 100%
.045 80-110 13-16 Argon 100%
1/16 90-130 14-16 Argon 100%

When should I use ER308L, ER309L, ER316L or ER347 filler metal?

ER308L (including ER308LSi) is predominately used on austenitic stainless steels, such as types 301, 302, 304, 305 and cast alloys CF-8 and CF-3. For high temperature applications such as in the electrical power industry, the high carbon 308H electrode provides better creep resistance than does 308L.

ER316L (including ER316LSi) filler metal should be used with ER316L and ER316 base metals. CF-8M and CF-3M are the cast equivalents of 316 and 316L, respectively.

Use ER309L (including ER309LSi) when joining mild steel or low alloy steel to stainless steels, for joining dissimilar stainless steels such as 409 to itself or to ER304L stainless, as well as for joining 309 base metal. CG-12 is the cast equivalent of 309. Some ER308L applications may be substituted with ER309L filler metal, but ER316L or ER316 applications generally require molybdenum and 309L contains no molybdenum.

Type ER347 stainless steel filler metal is ideal for ER347 and ER321 base materials because it matches these stabilized grades. CF-8C is the cast equivalent of ER347. Type ER347 filler metal is also suitable most ER308L filler metal applications.

Application
ER308L has the same analysis as type 308 except the carbon content has been held to a maximum of .03% to reduce the possibility of intergranular carbide precipitation. ER308L is ideal for welding Types 304L, 321, and 347 stainless steels. This is a suitable wire for applications at cryogenic temperatures.

How to Select Tungsten Electrode in TIG Welding (II): Pure Tungsten (Green)

Pure Tungsten (Color Code: Green)

Pure Electrode Tungsten electrode (AWS classification EWP, alloying color code: Green) consists of about 99.5% tungsten. It has the highest consumption rate of all electrodes, but typically less expensive than their alloyed counterparts.

These electrodes form a clean, balled tip when heated and provide great arc stability for AC welding with a balanced wave. Pure tungsten also provides good arc stability for AC sine wave welding, especially on aluminum and magnesium. It is not typically used for DC welding because it does not provide the strong arc starts associated with thoriated or ceriated electrodes.

Are ER308L TIG Welding rods rust proof?

er308l stainless steel
Question: Are these wires rust proof?
Answers:
1) Yes, but they are tig welding filler rods, not wires
By Kevin G. on January 22, 2016

2) Yes
By WeldingCity on January 22, 2016

3) They are stainless steel rods and resistant to corrosion under normal working conditions specified by AWS Spec. ER308. Thanks,
By WeldingCity on January 22, 2016

4) Yes
By Thomas Griffin on January 22, 2016

5) Yes but when you weld it brings the carbon to the surface so you can get some mild rust bit north like carbon steel you can passivated with acid that eats the carbon off the surface again also if you get any carbon steel in contact with your stainless steel it can cause it to rust 316 is more resistant to rust
By Martha L. Jones on January 22, 2016

6) I use them for mandrel’s for Lampworking. I’ve never had a problem with rust.
