Basic coated Electrode which is used to weld nickel-chromium-molybdenum alloys. Its applications include dissimilar joints between nickel-chromium-molybdenum alloys to stainless steels, carbon or low alloy steels. It is also used extensively in overlay cladding where similar chemical composition is required on the clad side. This alloy is suitable for applications where the temperature ranges from cryogenic up to 1800⁰F. |

Notes on usage:
Be sure to clean up the contaminations on the base metal, groove and pass to pass with stainless steel brush. Dry the electrodes at 250-300℃ for 2 Hour before using. Take out a batch of half day consumption and keep at 100-150℃ during welding process. Use back-step method to prevent arc starting from blowholes and hold for 3-5 seconds at every end—up. Maintain short arc length to prevent porosity problem. Do not exceed the range of recommended current. Over heat input might decrease the impact value.
It is hard to proceed by overhead or vertical position, flat position instead is recommended.
We do hereby certify that; the weld metal deposit, has been tested, mechanically and chemically and all results are comply with the requirements of specifications of Elkadesia for engineering industries and the Specification of ASME II part C SFA 5.01 Class C5 and level of tests in J or 5.
