DESCRIPTION

21/30431359 DC


This standard 21/30431359 DC BS EN ISO 18278-1. Resistance welding. Weldability is classified in these ICS categories:
  • 25.160.01 Welding, brazing and soldering in general

This part of ISO 18278 specifies procedures for assessing the generic weldability for resistance welding of uncoated and coated metals.

It is assumed for this and other linked standards that their application is entrusted to appropriately trained, skilled, and experienced personnel.

For the quality of welded structures, the relevant part of ISO 14554 is applicable. The specification of procedures is to follow guidelines as in ISO 15609-5.

The purpose of the tests are to

  1. compare the metallurgical weldability of different metals,

  2. assess the weldability of differing component designs, e.g. dimensional configuration, stack-up, projection geometry, etc.,

  3. 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, and/or

  4. compare the performance of resistance welding equipment.

Precise details of the test procedure to be used will depend on which aspect of items a) to d) will be evaluated relative to the welding result obtained.
