Yes Impact testing of HAZ will be as per Code...Code does not ask it process wise

Hi sir,
This is venkatesan from singapore.

Could you please clarify on the requirements of ASME Section Viii Div.1 Edition 2013 Section UG84.6?

PQR Base material : SA516 Gr.70 of thickness 38.1mm
Deposited weld metal like GTAW-4mm+SMAW-15mm+SAW-19.1mm

Question: HAZ impact specimen suppose has to be taken based on UG84.6, definitely GTAW process is difficult to cover.

Do we have to take impact for each process or just follow UG84.6 table?

Simply means, Impact test specimen will take for PQR/ PTC as per ASME VIII. Is based on thickness or process?

Thanks
Venkatesan
