In drawing Impact test requirements will give, if it's yes, you have to use impact tested WPS. If it's NO you can use without impact tested WPS.

Hello Experts,

Scenario

We have a weld joint where 10 mm thick SS pipe (P 8) is welded to 40 mm thick CS (P 1) flat cover. It is a partial penetration weld with 10 mm groove depth. The construction code is ASME Sec VIII Div. 1 and MDMT is -40 degree celcius. I am willing to use ER 309 LMo. 

Query

1. Do i have to use WPS with impact at or colder than -40 degree celcius, or only impact tested filler is enough? or, 

-YES

2. PQR without impact test will do if i am using non impact tested filler?

-NO.

Regards,

Pravin Katkar
