Plate heat exchangers that use welding as the joining method – do they fall under the category of pressure vessels? Can SW6 be used for stress calculations on them?

Can stress calculations be performed using SW6? For plate heat exchangers during welding, if the calculation results using SW6 are used, they are all unsatisfactory. So how is the strength calculation carried out?
Semi-welded heat exchangers are not subject to regulatory controls; Version 14 of the regulations seems to contain a similar description
