How to avoid the original welds and butt joints when patching equipment, and what to do if it is not possible to avoid them
It is best to cut along the weld and replace it with a new piece. If it cannot be avoided, 100% RT is required; various tests are inevitable, and the riveting and welding processes must be done properly
This inspection is necessary; repairing by patching can lead to deformation
It then depends on your riveting and welding techniques; the tooling needs to be well prepared
There are no major issues with alignment and welding; the main problem is that the container is quite heavy during patching, which may cause deformation. Once deformed, it becomes difficult to align and weld properly. What specific measures can be taken to ensure that the shape remains unchanged?

I recommend ASME PCC-2-2015 on the repair of pressure equipment and pipelines – it’s worth reading!
