Nozzle to Shell Weld
Nozzle to Shell Weld
(OP)
When a ASME code welder welds around a nozzle the angle between the shell and nozzle varies. The fillet weld size called out on the weld symbol represents that weld at a 90 degree angle. But you will not get the same weld throat you at the 90 degree angle when you get around to the 120 or 130 degree angle if you keep the weld legs the same throughout.
How do I make sure that my weld throat stays consistent all around the nozzle???

RE: Nozzle to Shell Weld
Depending on the ratio of the shell to the nozzle, the angle between the shell and the nozzle at the side zone can vary. The larger the angle, the smaller the throat for a given leg dimension.

RE: Nozzle to Shell Weld
If I took your suggestion and made a detail, what angle do I make it for? And how many details do I make?
Thanks
RE: Nozzle to Shell Weld
The AWS welding symbol uses the leg dimension, but as you noted, the throat dimension will get smaller in the side zone unless you increase the leg to maintain the required throat.
