What is this standard about?
BS EN ISO 17634 is an international welding standard, providing a classification system for tubular cored electrodes.
Who is this standard for?
- Suppliers, users, manufacturers and testers of tubular cored electrodes
- The construction, structural engineering and building industries
- Manufacturing industries, oil and gas, energy, chemical plants
- Shipbuilding
Why should you use this standard?
BS EN ISO 17634 offers the latest technical guidelines for welding consumables, relating to tubular cored electrodes. It is a combined specification, which means it provides for classification using two systems – the first based on the chemical composition of all weld metal (paragraphs and tables carry the suffix letter A), the second using a system based on the tensile strength alongside the chemical composition (carrying the suffix letter B).
The standard covers requirements for symbols for shielding gas and welding position, the usability characteristics of electrodes, mechanical tests and technical delivery.
What’s changed since the last update?
- This is the second edition of BS EN ISO 17634 and replaces the 2004 standard
- It has been systematically reviewed by experts, who have taken into consideration recent material, technological and industry developments
