[MW:1886] RE: 1885] Re: Fillet welding of shell to bottom joint of API 650 Tanks

No such restriction in API. However it states the welding of the shell to the bottom shall be practically completed before the welding of bottom joints that may have been left open to compensate for shrinkage of any welds previously made is completed.

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.   With Regards Ahmed Husain, ABS TPI Borouge2 --- On Mon, 4/6/09, shah B.K <b.k.shah@espasia.in> wrote: From: shah B.K <b.k.shah@espasia.in> Subject: [MW:1883] Re: Fillet welding of shell to bottom joint of API 650 Tanks To: materials-welding@googlegroups.com Date: Monday, April 6, 2009, 11:18 AM Hello Dear For shell to bottom weld gap is not required.
