BS EN ISO 14174:2019

What is ISO 14174-Fluxes for submerged arc welding and electroslag welding about? 

ISO 14174 is an International Standard on welding consumables. 

ISO 14174 specifies requirements for the classification of fluxes for submerged arc welding and electroslag welding for joining and overlay welding using wire electrodes, tubular cored electrodes, and strip electrodes. 

The main objective of ISO 14174 is to establish standardized classification of fluxes that impart high degree of reliability and performance for welding applications.  

Who is ISO 14174-Fluxes for submerged arc welding and electroslag welding for? 

ISO 14174 on fluxes for submerged arc welding and electroslag welding is relevant to: 

• Automotive, mechanical industry 
• Welding equipment manufacturers 
• Machine manufacturers 
• Manufacturers of pressure vessels 
• Earthmoving tools manufacturers 
• Shipbuilding industry 
• Railroad and locomotive construction 

Why should you use ISO 14174-Fluxes for submerged arc welding and electroslag welding? 

Granular flux used in welding is a type of granular insulative material that is made up of numerous small particles. In Submerged Arc Welding (SAW), the granular flux provides a blanket over the weld, which protects against sparks and spatter. 

ISO 14174 helps you standardize the classification of fluxes for submerged arc welding and electroslag welding processes. Having a common point of reference for classification improves the efficiency of submerged arc welding and electroslag welding. 

Adopting guidelines in ISO 14174 help you improve in quality and efficiency of submerged arc welding and electroslag welding by applying standard classification of fluxes in the welding process using wire electrodes, tubular cored electrodes, and strip electrodes. As a result, you can make the right selection of flux as per your specific application, for enhanced welding quality, reliability and equipment performance. 

What’s changed since the last update? 

BS EN ISO 14174:2019 supersedes BS EN ISO 14174:2012, which is withdrawn. BS EN ISO 14174:2019 includes some technical changes with respect to BS EN ISO 14174:2012. These include: 

• Subclause 5.4.3 now clarifies burn-out 
• ISO 18724 has been added to Clause 2 
• Table 3 has been expanded 
• Table 5 for flux class 2, welding current and voltage have been revised 
• An example of a Z option has been added
