Check the point of initiation / pattern defects and confirm the fracture locations.

Dear Experts

A PQR sample has been welded per below procedure;

SB-209 Grade 5183

THK; 40 mm

Process; GTAW

Filer metal; ER5183

Shielding gas; Argon

Preheat Temp; 70°C/Interpass Temp; 100°C

but all four bend samples rejected due to facture, meanwhile the tensile result is less than acceptable criteria.

would you please advise me in regards to the reason for this failure.

Thanks Indeed
