Dear Friends,

 

I have tested one PQR where Impact testing (GTAW weld) got failed at -48°C & -35°C also;

 

Impact values

9 joules at -48°C

12 Joules at -35°C

 

 

I had received Filler wire with 3.1 certificate having impact tested at-50°C; kindly advise

 

Heat Input max

1.8Kj/mm for other runs

 

Kindly advise
