RE: [MW:31726] Imapct toughness testing on weld joint of material SA 516 Gr70

Dear  Shahil,

In order to help you identify the problem, please report the following:

1. For the Charpy impact test, was the UG-84 ASME VIII-1 instructions followed?

2. What were the values of the impact test in ft-lb?

3. What was the test temperature?

4. Is the WPS qualified with the supplemental  Charpy impact test?

5. Regarding the sample: is the surface flat and does it appear shiny?

6. What welding process was used to make this pressure vessel?

7. The base material was selectionated as SA-516 Gr.70N?
