One option to using strip liners is to evaluate strip cladding. The strip is the welding electrode and is deposited by SAW or ESAW processes for high deposition rates. The strip cladding will be fused to the carbon steel substrate, and will not warp from post weld heat treatment of the vessel.If these are loose strip liners (like wall paper), they will be seal welded along the perimeter. I would consider straight E309L weld rod for seal pressure vessel steels thyssenkrupp Strip surfacing weldingIn addition to the above discussion of strip cladding you should take a look at this site.

Where are the disbonding cracks in stainless steel?
Examination of the interface microstructures and disbonding cracks showed that the cracks were located in the compositional/microstructural transition zone within about 100µm of the fusion boundary. In this region, martensite was present after PWHT, giving rise to high hardness and susceptibility to hydrogen embrittlement.See all results for this questionWhat kind of steel is used for pressure vessels?Cryogenic nickel steel for liquid gas vessels and pressure vessels. X-COR ® pressure vessels can withstand higher loads and temperatures with no significant increase in wall thickness.See all results for this questionWRC bulletin.
