Can a report prepared for the welding procedure qualification of titanium pressure vessels using TA2 be used to develop a welding procedure (welding operation instruction) for TA10?

So do you think the welding procedure qualification for S30408 can be applied to S30403?

The rule is: when the base material category changes, it is necessary to re-evaluate the categories of TA2 and TA10; both are placed in the same group. . . The necessary basic conditions have been met without changing the welding method.
