This document specifies requirements for resistance spot and seam welding for aerospace applications. This document 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.st edition 2013-01-15 Welding for aerospace applications — Resistance spot and seam welding Soudage pour applications aérospatiales — Soudage par résistance par points et à la molette Reference number ISO 16338:2013(E) ？ ISO 2013 ISO 16338:2013(E) COPYRIGHT PROTECTED DOCUMENT ？？ISO 2013 All rights reserved.
