E 70C-6M

Suitable welding positions

CWB to CSA W48-14
Classification: E490T15-M21 A3-CS1 -HS (E492C-6M-H8) AWS/ASME A5.36/A5.36M:2016

Typical applications

Butt and fillet welding of steel structures such as construction machines, industrial machinery, and buildings, etc.

Characteristics on usage

  • Very good Charpy V notch toughness at low temperatures
  • Good penetration and excellent welding characteristics
  • Excellent product for fillet welding
  • High tolerance to rust, primer and mill scale (compared to E70C-3M)
  • Designed for semi-automatic and automatic single and multiple pass welding
  • Slag quantity is almost the same as solid wire (ER70S-6) which allows for multiple pass welding to be performed without having to remove the slag
