(two) Warmth remedy is not expected once the welding or brazing of weldable reduced carbon sections to attachments of similar substance that have been previously welded or brazed to the very best or base of cylinders and correctly warmth treated, provided such subsequent welding or brazing would not make a temperature in extra of four hundred °File in any Section of the top or base content.
(4) Establish porosity of filling and tare weights; verify compliance of marking with prescribed demands; obtain important copies of steel shell reviews prescribed in paragraph (b) of the area; and furnish complete check reports required by this specification to the person who has done the maker on the cylinders and, on ask for, for the purchaser.
