70S-6 Mild Steel MIG Wire

INTRODUCTION

Aufhauser 70S-6 contains higher levels of manganese and silicon for stronger deoxidizing power where stringent cleaning procedures are not possible. The ER70S-6 is intended for both single- and multiple-pass welding. This wire has been designed to provide x-ray quality porosity-free welds and the highest tensile strength (as welded) of the plain carbon steel wires. The high silicon content increases the fluidity of the weld pool, creating a smoother bead appearance and resulting in minimal post-weld grinding. Aufhauser 70S-6 is excellent where poor fit-ups or rusty and oily plates may be used. It is especially suited for sheet metal applications. These electrodes withstand high currents with CO2 shielding, even when welding rimmed steels.

APPLICATIONS

  • Welding steels with dirty or rusty surface
  • (UNS numbers K02600, K02801, K02001, K02700)
  • Single-pass welding of killed, semi-killed, and rimmed steels
  • May be used for some multi-pass applications
