Hot Topping Validation
Hot Topping Validation
(OP)
I have been investigating Charpy test failures in our steel foundry recently and am evaluating our process. One item of concern is a change that was made a couple years ago to our hot topping. Can someone suggest a test that can be done to validate that the hot topping is still working properly? I have put out a call to the supplier, but haven't heard anything yet.
Thank you for your suggestions.

We used to measure both when we were making changes in molds or topping.
