What is this standard about?
This is the first part of a two part standard on resistance welding weldability. This part specifies procedures for assessing the generic weldability for resistance welding of uncoated and coated metals.
Who is this standard for?
- Trained, skilled and experienced welding contractors
- Resistance welding equipment manufacturers
- Test houses
- Specifiers
- Health and safety managers, consultants and inspectorates
- Risk assessors
- Authorised training and qualification bodies responsible for ensuring that welding training and examinations adopt best practice
Why should you use this standard?
It covers the weldability of components, preparation of welding equipment, test procedures and test reports. The purpose of the tests are to:
- Compare the metallurgical weldability of different metals
- Assess the weldability of differing component designs, e.g. dimensional configuration, stack-up, projection geometry etc.
- Investigate the effect of changes in welding parameters such as welding current, weld time, electrode force or complex welding schedules including pulse welding, current stepping etc. on weldability
- Compare the performance of resistance welding equipment
NOTE: For the quality of welded structures, the relevant part of ISO 14554 applies. The specification of procedures follows guidelines in ISO 15609-5.
What’s changed since the last update?
The standard was systematically reviewed by technical experts to ensure its continued market relevance. This standard is a technical revision of the 2004 version which has been withdrawn.
