Resistance welding - Weldability - Part 2 : alternative procedures for the assessment of sheet steels for spot welding

ISO 18278-2:2004 specifies a laboratory test procedure for the determination of the acceptable welding current range and the assessment of electrode life using a multi-spot test with specific conditions. ISO 18278-2:2004 is applicable for the assessment of the weldability of uncoated and coated sheet steels of thicknesses up to 3 mm. The test procedure specified in this International Standard and the results obtained, apply only for the introduction of a new type or batch of material.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
