Characteristics and Application

AWS A5.11 ENiCrFe-3 Welding rod, welding electrode is a low hydrogen type covered electrode containing 65Ni, 15Cr, 8Fe, 7.5Mn, 2Nb. The welding is suitable for all positions with good heat resistance, oxidizations resistance and good corrosion resistance. It produces toughness under low temperature. It is applied in the Inconel welding and dissimilar metals welding. Proper base metals are also including ASTM B 163/166/167/168. All-position welding is available when the diameter is 3.2(mm) or less, otherwise, horizontal and flat positions are available only.

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.
