Applications

The N-10018-D2 is designed for applications requiring at least 100,000 psi tensile strength, good ductility and crack resistance. Typical applications include manganese-moly castings, alloy forgings, structurals and pressure vessels applications in either the as welded or stress relieved conditions.

Characteristics

N-10018-D2 is a high quality electrode designed for high tensile steels and manganese-molybdenum steels. The coating is specially formulated to resist moisture pick-up under conditions of high heat and humidity. This electrode offers resistance to moisture reabsorption which helps prevent hydrogen cracking and aids in the elimination of starting porosity. Definitely an electrode with high operator appeal.

Notes on usage

(1)   Dry the electrodes at 350-400°C for about one hour before use and store the electrodes at 100-150°C after drying them with attention to keep away from moisture.

(2)   Adopt back step method or strike the arc on a small steel plate prepared for this particular purpose, because arc striking on base metal is in danger of initiating cracking.

(3)   Keep the arc as short as possible.

(4)   Preheat at 100-150°C. The temperature to be applied varies in accordance with plate thickness and kind of steel to be welded.

(5)   Pay attention not to exceed proper heat-input because excessive heat-input causes deterioration of impact values and yield strength of weld metal.
