KUNWU ER70S-6 Premium Mild Steel TIG Welding Filler Rods 0.040" x 40"

Primarily used for single-pass welding of killed, semi-killed, and rimmed steels,
Because of the added deoxidants, these filler metals can be used for welding steels that have a rusty or dirty surface

500 MPa level carbon steel filler metal, can be used in the welding of carbon steel and low alloy steel in the corresponding strength grade, which can be used in engineering machinery, ship, vehicle manufacturing, petrochemical and other industries

Straight length of 36 inch packaged in a PVC tube (Random Color), 1, 2, 5, 10 Lbs-Pack can be shoosed

Welding Positions: All Positions

PLEASE NOTE: Due to Long term inventory, random old packaged tube may have little rust on some rods, can be used for sure after sandpaper sanding before use and will not affect the welding quality


Description of ER70S-6
Electrodes and rods of the ER70S-6 [ER48S-6]

ER70S-6 [ER48S-6] rods 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). Typical base metal specifications are often the same as those for the ER70S-2 [ER48S-2] classification.
Applications of ER70S-6

ER70S-6 primarily used for single-pass welding of killed, semi-killed, and rimmed steels, may be used for some multipass applications, as a kind of 500 MPa level carbon steel filler metal, can be used in the welding of carbon steel and low alloy steel in the corresponding strength grade, which can be used in engineering machinery, ship, vehicle manufacturing, petrochemical and other industries.
Welding Parameters

ER70S-6 take CO2 or 80%Ar+20%CO2 gas shielded arc welding. The welding spatter is small, and it has beautiful appearance, high cladding efficiency and small weld metal porosity sensibility.
