Medium and High Tensile Steel

CNM (SPL) M

AWS: SFA 5.5 E12018M EN ISO CODE: 18275-B E 83 18 N4C2M2 A H5
  • Basic coated electrode with a stable and smooth arc, easy to strike and restrike.
  • Low spatter and good bead finish.
  • Welds are of radiographic quality.
  • The weld metal displays good crack resistance and produces sound weld metal possessing excellent strength combined with good impact properties at subzero temperature.                                                     
  • It is suitable for joining many high strength, low alloy or micro alloyed steels to themselves or to lower strength steels, including carbon steels. Ideally suited for welding earth moving equipments and other heavy equipments.
Precaution

1. Ensure the electrodes are dry. Re-dry the electrodes at 300°C for 2 hours.

2. Use short arc and stringer beads.

3. Use a carefully formulated welding procedure with preheat and post weld heat treatment.
