## Overview

The KUNWU ER70S-6 1/16" x 18" x 5 Lb Economical Mild Steel TIG Welding Rods are engineered for superior performance in various welding applications. With a strength of 500 MPa, these rods are perfect for single-pass welding of carbon and low alloy steels, even on less-than-perfect surfaces. Packaged conveniently in a PVC tube, they are designed for all welding positions, making them an essential tool for professionals in engineering, shipbuilding, and petrochemical industries.

## Description

ER70S-6 [ER48S-6] are primarily used for single-pass welding of killed, semi-killed, and rimmed steels, but may be used for some multipass applications. Because of the added deoxidants, these filler metals can be used for welding steels that have a rusty or dirty surface, with a possible sacrifice of weld quality depending on the condition of the surface. ER70S-6 filler metals are used extensively to produce high quality, high toughness welds with the GTAW process. These filler metals are also well suited for use in single side, melt through welding without a protective root shielding gas on the backside of the joint. Typical specifications for these steels are ASTM A 36, A 285-C, A 515-55, and A 516-70, which have UNS numbers K02600, K02801, K02001, and K02700, respectively. ER70S-6 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. It take CO2 or 80%Ar+20%CO2 gas shielded arc welding. The welding spatter is small, and it has beautiful appearance ER70S-6 Electrodes and rods of the ER70S-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 ER70S-2 electrodes when using either binary or ternary argon shielding gas mixtures per the AWSA5.32 specification. Typical base metal specifications are often the same as those for the ER70S-2 [ER48S-2] classification.
