What is ISO 156091-Arc welding procedures for metallic materials about? 

ISO 15609 series covers specification and qualification of welding procedures for metallic materials. 

ISO 156091 is the first part of the muti-series of documents that specifies requirements for the content of welding procedure specifications for arc welding processes. The variables listed in ISO 156091 are those influencing the quality of the welded joint. 

The main objective of ISO 156091 is to improve quality assurance systems in the field of welding. 

Who is ISO 156091-Arc welding procedures for metallic materials for? 

ISO 156091 on arc welding procedures for metallic materials is relevant to sectors such as: 

  • Oil and gas 
  • Nuclear and energy 
  • Construction 
  • Automotive 
  • Aerospace 
  • Shipbuilding and marine 

Why should you use ISO 156091-Arc welding procedures for metallic materials? 

ISO 156091 specifies requirements for the content of welding procedure specifications for arc welding processes. The variables listed are those which influence the quality of the welded joint. 

ISO 156091 helps you standardize the specification and qualification for the content of welding procedure specifications for arc welding processes. Having a common point of reference for classification improves the efficiency of arc welding processes across the welding industry.  

Organizations should use ISO 156091 for help with the design, materials and condition of their arc welds. As a result, you can enhance quality assurance and quality management systems in the field of welding. This can ultimately help build trust and gain acceptance across the welding industry and supply chain. 

What’s changed since the last update? 

BS EN ISO 156091 supersedes BS EN ISO 156091:2004, which is withdrawn. BS EN ISO 156091 includes some technical changes with respect to BS EN ISO 156091:2004. These include: 

  • The former Note 1 in 4.1 has been moved to regular text 
  • Clause 2 has been updated and editorial changes have been made 
  • Surface conditions have been added in 4.4.4 
  • Subclause 4.4.10 has been technically revised and arc energy has been added in 4.4.17 
  • Annex A has been revised
