Incoloy 800HT. / Incoloy 800HT. By welder5354 Date 04-07-2009 04:00. Hi all, i'm presently welding a procedure for Inconel. I'm welding Incoloy 800HT to Incoloy 800HT. The problem is that i'm getting a lot of porosity. The filler wire that i'm using is AWS ERNiCr-3. Would AWS ERNiCrMo-3 be a better choice for Incoloy 800HT welding to itself.

Incoloy 800 is a popular nickel and chromium based alloy designed to resist corrosion in extreme temperatures and environments. It also has excellent mechanical properties such as high strength, good oxidation resistance, and excellent carburization characteristics. From cryogenic temperatures all the way up to 1500°F (816°C), Incoloy …
