CNM (SPECIAL)

AWS: SFA 5.5 E12018-G EN ISO CODE: 18275-B E 83 18-G A H5

CNM (SPL) is a special formulated electrode to deposit a very high strength weld metal. The weld metal possesses high strength and toughness and is ideally suited for welding high strength steels.

Precaution

1. Ensure the electrodes are dry. Re-dry the electrodes at 250-300 C for one hour.

2. Use short arc and stringer beads.

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