[MW:1885] Re: Fillet welding of shell to bottom joint of API 650 Tanks

Hi Mr. Shah,
 
Yes, I totally agree with you. But here due to some fabrication and erection mistake, there is a gap of 10 mm. As per AWS D1.1, upto 5mm can be accepted. As applicabe code is API 650, I wanted to know if there is any reference in this code.

Hello Dear

For shell to bottom weld gap is not required. Shell Plate should be completely contact with bottom plate.
