ISO/TC 44/SC 14 - Welding and brazing in aerospace

This document specifies requirements and test methods for the qualification and re-qualification of laser beam machines for metal powder bed fusion additive manufacturing for aerospace applications. It can also be used to verify machine features during periodic inspections or following maintenance and repair activities.

This document specifies requirements for the qualification of operators of laser metal powder bed fusion machines and equipment for additive manufacturing in aerospace applications. This document is applicable if the operator qualification testing is required by contract or by application standards in the field of aerospace.

This document specifies the requirements for fusion welding of aerospace hardware. It is to be used in conjunction with the design/engineering authority's design documents or their accepted data. This document covers the processes given in Table 1 and material groups given in Table 2.

This document specifies acceptance criteria for fusion weldments on metallic components. It is to be applied provided it is referenced or approved by the responsible engineering/design authority. This document covers the following processes given in Table 1 and the material groups given in Table 2.

This document specifies requirements for the qualification of welders and welding operators for the fusion welding of metallic materials for aerospace applications. NOTE Success in the test is an essential precondition for the qualification of welders (3.2) and welding operators (3.3) in new production and repair work in aerospace. However, welding equipment operators (3.4) do not need to be qualified according to this document.

ISO 19828:2017 specifies the requirements for visual inspection of welds in metallic materials and requirements for qualification and certification of personnel for visual weld inspection. ISO 19828:2017 is also applicable to the visual inspection of the joint prior to or between welding sequences, and of brazed joints. In this case, the contents of theoretical and practical training will need to be adapted accordingly.

ISO 16338:2017 specifies requirements for resistance spot and seam welding for aerospace applications. ISO 16338:2017 does not apply if resistance welding is simply an intermediate operation and does not affect the quality of the end product, for example when tacking basic parts prior to assembly with another process. Resistance welding of dissimilar material group combinations is not covered by this document. Safety and health issues and concerns are not covered by this document.

ISO 17533:2015 specifies appropriate welding/brazing design information on drawings serving to ensure fit, form and function of welded/brazed joints, and is applicable to welded and brazed metallic component parts used in aerospace construction.

ISO 11745:2010 specifies a qualification test for brazers engaged in manual brazing of parts and brazing operators in aerospace construction.

ISO 16338:2013 specifies requirements for resistance spot and seam welding for aerospace applications. It does not apply if resistance welding is simply an intermediate operation and does not affect the quality of the end product, for example when tacking basic parts prior to assembly with another process. Resistance welding of dissimilar material group combinations is not covered by ISO 16338:2013.

ISO 24394:2008 specifies requirements for the qualification of welders and welding operators for the fusion welding of metallic materials for aerospace applications.
