Re: [MW:10191] Tungsten inclusion appeared in WQT


Dear Mr Karthi,
 
                      Thanks for your reply and it seems i had over looked at it. Now it is so clear that we can accept it even upto 3mm size of Tungsten inclusion. I have even refered B31.3
and it accepts 1/3 't' where t-thickness of the joint.
 
Again thanks for your immediate response.
 
regards
Ilan

Dear experts,
 
                As far I know that slag inclusion allowed 3mm size as per secIX section QW-191.2.2(2)(b). Tungsten inclusion is not accepted kindly advise me if i am wrong.

Ilan
