It is the allowable stress of the steel plate at the design temperature

It is the allowable stress of the steel plate; standards stipulate that the strength of the weld must not be lower than that of the base material.

It’s of course the allowable stress of the steel plate; after multiplying it by the weld coefficient, we get the allowable stress for the weld area

It should be the allowable stress of the steel plate at the design temperature
