TS EN ISO/ASTM 52926-5

TS EN ISO/ASTM 52926-5 addresses qualification principles for operators working in metal additive manufacturing with directed energy deposition using an arc source (DED-Arc/M). In practical terms, it defines the capabilities, responsibilities, and assessment areas expected for personnel involved in this specific metal-part production process, including the criteria used to judge both theoretical knowledge and hands-on performance.

What DED-Arc/M operator qualification means

DED-Arc/M is a directed energy deposition process in which an electric arc is used as the heat source to build material onto a part layer by layer. In general technical terms, operator competence in such a process typically involves understanding machine setup, monitoring process conditions, preparing the workpiece, maintaining process control, and recognizing basic quality-related issues. This standard provides a qualification framework tailored to that operator role in the DED-Arc/M environment.

A key feature of the document is that it looks beyond simple machine operation. It connects the operator role with the process knowledge and practical discipline needed to support consistent production in industrial settings. By covering both theoretical and practical assessment, it distinguishes between knowing the process and being able to carry out the related tasks reliably. The result is a structured basis for qualifying AM machine operators in general industrial applications.
