HAZ Too High in One Spot
HAZ Too High in One Spot
(OP)
There have been a few times when welding on a coupon (625-4130) that when the hardness comes back, there is always one spot on the outer edge that is significantly higher than the rest. Ex: 251,254,274. Any ideas on how to correct this or what is calling it?

I'd also recommend providing more detail in those forums, as in "on the outer edge" of what? The HAZ, the OD, ID, base metal, before or after PWHT, etc.
