Need help with filler rod suggestion.I have a Case Hardened Gear made out of 8620 Material. Only the teeth have been hardened. The bore needs to be welded with approx. .020 material build up to clean it up. Heat is an issue, as the Hardening cannot be compromised. What filler rod do you suggest, and would pre or post heating be necessary.Thanks for your input.
Reply:Since your not going back to heat treat, any E70 will work well, E80Ni1 will bring up the toughness.8620 is very safe to weld with minimal pre-heat, but you'll need to stop welding when the area near the teeth gets to 400°F.Matt
Reply:Thanks Matt,That's what I was hoping to hear. |
