Welding wire for ASTM A 621

Welding wire for ASTM A 621

(OP)
Dear All,

What is the filler wire to be used for MIG welding for welding of sheet metal ASTM A 621 ?

RE: Welding wire for ASTM A 621

A general purpose, mild steel wire should be sufficient. One example is Lincoln ER70S-6.
I don't practice much in this area anymore, so there might be something better out there.
A bit more information on your application would be helpful.

RE: Welding wire for ASTM A 621

Agreed, SFA 5.18 ER70S-6.

See excerpt below from the referenced SFA specification;
A7.4 ER70S-6 [ER48S-6]. Electrodes and rods of the
ER70S-6 [ER48S-6] classification are intended for both
single- and multiple-pass welding. They are especially
suited for sheet metal applications, where smooth weld
beads are desired, and structural and plate steels that have
moderate amounts of rust or mill scale. These electrodes
permit the use of higher current ranges with either CO2
(AWS A5.32 Class SG-C) shielding gas or with mixtures
of argon and oxygen (AWS A5.32 Class SG-AO-X) or
argon and carbon dioxide (AWS A5.32 Class SG-AC-Y).
However, these electrodes do require a higher level of
oxidation than the previously described electrodes when
using either binary or ternary argon shielding gas mixtures
per the AWS A5.32 specification. Typical base metal specifications
are often the same as those for the ER70S-2
[ER48S-2] classification.
