[MW:3574] Re: min thickness qualified in AWS D1.1

Hi,

 

Below 16 mm if impact is not required by design , then you can put qualified range from 3.2 mm  instead of 16,

 

The limitation because of heat input and rate of coling will play vital role when Impact required  ,

 

You cannot genaralise the above factors for below 16 mm and above 16 mm .

Hi All

1-does anybody know why AWS is given a limitation for min thickness qualified if charpy is carried out for wps qualification?(according to table 4.6)

i suppose that the max thickness is critical for toughness.

2-now for written qualification range for thickness in wps,i must follow table 4.6 or 4.2

regards

 

Thanks & regards,
