I recall two instances of weld repairs to Crude columns in service that led to catastrophe. Do be extraordinarily careful!

As I am not specialized in pressure vessel design so should study it based on your comments and come back.

Still I will try to gather information and share with you, if I get any.

Welded Encapsulations are one of many topics addressed in ASME PCC-2 Repair of Pressure Equipment and Piping Part 2. They're used commonly enough, and easy to fabricate out of materials readily available at most refineries and upstream facilities. Nothing secret or special about them, but it does help to have a pretty thorough understanding of vessel design, and occasionally, design by analysis.
