er70s-2 vs er70s-6

https://www.sino-welding.com/news/17362.html

Type ER70S-2 is the most popular Tig rod for welding carbon and low alloy
steels and is a triple deoxidizing steel wire used for both TIG and MIG welding
applications. Type ER70S-6 is also available in cut lengths for purchase and is
a very popular MIG wire for TIG welding.

What does er70s 6 mean?
ER70S6 wire meets AWS A5.18 specifications. The designations are as follows: ER
indicates the filler metal that can be used as an electrode or rod. 70
indicates the minimum tensile strength in 1000 psi increments when tested in
accordance with this specification for the weld metal produced by the
electrode.

What does er70s 2 mean?
er70s 2 is a composite deoxidizing wire that contains small amounts of
zirconium, titanium, and aluminum in addition to the manganese and silicon
deoxidizers characteristic of the wire set. er70s 2 is widely used for
staggered welding of small diameter wires that utilize short-circuit arc type
transfer.



ER70S2 vs ER70S6 wire/rod: Which is better?


ER70S2 vs ER70S6
Both ER70S2 and ER70S6are MIG and TIG compatible electrodes that can be used
for all light welding applications such as sheet metal and tube work. These
wires have nearly identical specifications except for the better yield and
tensile strength of ER70S6. The higher silicon content in ER70S6 allows the
filler metal to be more fluid than other filler metals and appears to float the
oxide to the surface, providing a better weld on blocked surfaces.

Welding wire is a metal rod that is used to create a heated arc that joins two
metal workpieces together.

Welding wire can be of different types and is used in various welding
processes.
Welding wire is a gas shielded electrode with a variety of mechanical and
chemical properties, arc behavior, quality, and cost.
