ASME SFA 5.18
WT 70S-6 is a mild steel wire that was made to give high quality welds from heavy duty, high speed spray transfer applications to light duty, low speed applications. It can be used in both single and multipass welding. This electrode allows for higher current with shielding gases of CO2 or a mixture of Ar and O2 or Ar and CO2. WT 70S-6 welds a stable arc with low spatter giving a weld bead that ties evenly with the sides allowing for a smooth appearance. Typical applications include frame fabrication, pipe fabrication, construction, pressure vessels, and in high-speed robotic and automatic welding applications.
