Electrodes for Low Temperature Service

Nimotherme-NM1 is a low-hydrogen electrode, which contains about 1% Nickel and 0.5% Molybdenum. This electrode can be welded without PWHT. Some typical applications include the welding of similar composition high-strength low-alloy or microalloyed structural steels.

1. Re-dry the electrodes at 250-300°C for one hour, as per our standard recommended practice.

2. Use short arc, stringer bead, and smallest size of electrode, minimum current to ensure minimum heat input.
