Characteristics and Application
AWS A5.11 ENiCrMo-3 Welding rod, welding electrode is a nickel based low hydrogen type covered electrode (for DC) containing 60M, 22cr 5Fe, 9Mo, 3.5Nb. The product provides excellent heat and corrosion resistance. It is widely used for chemical plant, nuclear reactor, Inconel 625, 9%Ni steel and dissimilar metals welding All-position welding is available for stick electrodes with a diameter of 3.2(mm) or less in size. Proper base metals are also including ASTM B443/444/446, Incon 625/825/Alloy20/AlIoy25_6Mo Mone1400.

Notes on usage:
1. Be sure to clean up the contaminations on the base metal, groove and pass to pass with stainless steel brush.
2. Dry the electrodes at 350-400℃ for 60 minutes before using. Take out a batch of half day consumption and keep at 100-150℃ during welding process.
3. Use back-step method to prevent arc starting from blowholes and hold for 3-5 seconds at every end—up.
4. Maintain short arc length to prevent porosity problem.
5. Do not exceed the range of recommended current. Over heat input might decrease the impact value.
6. It is hard to proceed by overhead or vertical position, flat position in stead is recommended.
