Design choices for pressure vessel welds
Thread Content
Experts, I’m a newcomer to the field of design. I really want to understand how to design or select welding structures for pressure vessels – for example, when welding heads to cylinders, how should one determine the dimensions of the grooves and weld angles? Sometimes, there are weld structures for which no examples are provided in the standards. How should such weld structures be designed and selected? It would be great if you could explain this design process to me in detail and systematically. Thank you!
In accordance with Appendix D of GB/T150.3-2011 and Chapter 18 of HG/T20583-2011
In other words, the examples provided serve as references for choosing the dimensions of the weld seam and the weld angles, but how can we determine whether it can withstand sufficient pressure or whether the strength of the weld seam is adequate? Thank you
Choosing according to the standards is the right approach; it’s also important to pay attention to the compatibility between the welding material and the base material, as there should be no issues with strength.
I think it’s better to follow the 150 guidelines carefully; that way you’ll understand many things better. You might also have many questions, and if you’re not familiar with the standards, you won’t be able to understand the answers to many of those questions properly
