What is ER70S G?

What is ER70S G?

ER70S-G. Characteristics and typical fields of application. A copper coated, manganese-silicon alloyed GTAW wire for welding of all general engineering and structural steels with minimum yield strength of max 400 MPa. High levels of silicon and manganese for use on slightly contaminated base materials.

What do the numbers on TIG wire mean?

The first two digits represent the resulting weld’s minimum tensile strength, measured in pounds per square inch (psi). The fourth digit represents the coating type and the type of welding current (AC, DC or both) that can be used with the electrode.

Can I use MIG wire for TIG filler?

Mig welding wire from a spool can be used for Tig Welding.

What does er stand for in ER70S 6?

As an example, for a commonly used solid wire — AWS ER70S-6 — the “ER” indicates that the filler metal is an electrode or rod; the “70” signifies that it has a tensile strength of 70,000 pounds per square inch (psi); and the “S” means that it is a solid wire.

Does TIG welding use a filler rod?

In TIG welding, you feed the filler rod into the molten puddle by hand. Your choice of filler rod is extremely important as the rod must correctly match the alloy of the material you will be welding. 4043 is a good general filler metal for most aluminum applications.

What does the 1 stand for in E6010?

E6010 electrode Specification & classification E stands for Electrodes for SMAW or stick welding. The next two digits i.e. 60 indicate the tensile strength of weld deposit is 60 KSI or 60000psi. The next digit 1 indicates it is all position electrode which mean F, V, OH, H positions.

What is the difference between ER70S 2 and ER70S-6?

Both the wires can be used for similar jobs due to identical capabilities. The major difference between the two products is prominent when the user is operating on contaminated or rusted surfaces, in which case the ER70S6 provides better penetration and higher quality of welds.

What is the difference between ER70S 3 and ER70S-6?

One vendor used 70S-6 for a GTAW root pass while the other used 70S-3 for a GTAW root pass. From the ASME material specification, 70S-6 has higher manganese and silicon and thus better suited for welding materials with mill scale.
