Filler would be ERNiCu-7. You will need to qualify a weld procedure in order to legitimately repair the casting. Keep in mind that you want to control your interpass to 300-350f Max and that good pre-cleaning and interpass cleaning are necessary to successfully weld this material. Fully remove the defect prior to welding.

Once the weldment reaches an ambient temperature, make sure to perform PT. This is a must.
