ISO/AWI 17927, Welding for aerospace applications - Fusion welding of metallic components : a new series approved !

ISO/TC 44/SC 14 "Welding and brazing in aerospace" has just approved a new series : ISO/AWI 17927, Welding for aerospace applications - Fusion welding of metallic components, Part 1: Process specification and Part 2: Acceptance criteria.

Since fusion welding is a widely used joining procedure within the aerospace industry, ISO/TC 44/SC 14 proposed the creation of an international standard for fusion welding in aerospace which is mainly based AWS D 17.1 and DIN 29595.

Although established internal company specifications are established, ISO/TC 44/SC 14 agreed that the development of an International Standard specifically designed for fusion welding of metallic components would give the wider aerospace industry the opportunity to utilise the guidelines identified within this proposed standard and thus, establish a minimum level of prerequisite for fusion welding of metallic components used in the manufacture of aerospace components.

The series should be published in 2021.

Part 1 specifies acceptance criteria for fusion weldments on metallic components. It shall be applied provided it is referenced or approved by the responsible Engineering/Design Authority. When the responsible Engineering/Design Authority has referenced a different specification for acceptance criteria, these criteria shall take precedence.

Part 2 specifies the requirements for fusion welding of aerospace hardware. It is to be used in conjunction with the Engineering Authority’s design documents or their accepted data. When conformance to this specication is stipulated in contract documents, all provisions of this specication shall be complied with, except for those provisions that the Engineering Authority or contract documents specically exempt, or those optional provisions that shall be applied when specied by the contract documents.
