Problems with ear supports welded to girth welds
Thread Content
There is a normal pressure equipment, and the ear support is welded to the cylinder ring weld. Is this okay? If not, what should be done?
Go check JB4735 to see what it says and what the contract requires.

It's absolutely possible, but the welds must be inspected and smoothed.
Weld inspection and grinding. Leave a small section at the top and bottom of the weld seam unwelded.
Yes, but the welds covered by the ear seats need to be 100% radiographic or ultrasonic tested, and the welds must be polished flush with the base metal.
Absolutely. The weld seam covered by the ear seat is polished until it is flush with the base material and 100% radiographic or ultrasonic tested. A small section of the connection between the circumferential weld and the ear seat is left unwelded.
Which standard requires 100% flaw detection?
The welded joints covered by the backing plate should be 100% RT or UT, which is the requirement of GB150.4. But it's for pressure vessels.
Why leave a section unsoldered?
