Basis for ISO 3834  series of welding standards

As is well known, weld quality is achieved by sound welding, not by inspection. Inspection, however, provides a check of the reliability of the product, but cannot improve poor quality. Therefore, welding requires continuous control and/or to follow documented procedures. Certifications such as ISO3834 can build a robust quality management systems thus attracting more customers.

Genesis of ISO-3834

A member of the International Union of Technical Associations and Organisations (UTAO), IIW is a part of the International Council for Engineering and Technology (ICET), one of the twelve key formal umbrella organisations associated with UNESCO.

The experts of International Institute of Welding (IIW) have supplied the technical basis of the great majority of welding standards issued by the International Standards Organisation – ISO.

Since 1989, IIW has been recognised by ISO as an International Standardisation Body to prepare the final texts of international welding standards.

What is ISO 3834?

ISO3834 is an international standard created by welding professionals. ISO 9001 provides the requirements for a quality management system; it does not establish requirements for products. The standard on the other hand, does provide the quality requirements for a welded product.

It specifies requirements relating only to the quality of the welded product. Encourages a proactive process orientated approach to managing and controlling welding   product quality in a workshop or on site. Also, gives a Factory Control System to control activities for the manufacture of the product.

Why adopt ISO 3834 when we have ISO 9001?

ISO 9001 is a comprehensive standard that lays down quality management system requirements for any organisation. However, the standard does not prescribe specific details for “special processes”. Welding is regarded as a ‘special process’. ISO 3834 was developed to identify all factors that could affect the quality of welded product and which need to be controlled at all stages, before, during and after welding.

What are the benefits of specifying the ISO 3834 Standard for the purchaser & supplier?

  • More assurance of contract delivery dates
  • Greater assurance of the quality of welded products
  • Greater reliability and performance of plant
  • Reduction in maintenance costs
  • Reduction or elimination of third party inspection costs
  • More competent suppliers of welded products

What are the benefits of using the ISO 3834 Standard for the manufacturer?

  • Less rework
  • Jobs completed on time
  • Local and international recognition as a competent organisation
  • Meet the welding-related requirements of ISO 9001
  • More efficient coordination of welding activities
  • More pro-active and responsible workforce
  • Increased opportunities and capability to bid on jobs
  • Cost savings – more efficient technology
  • Reduced surveillance audits and inspections by purchasers with significant savings

What are the benefits of using the ISO 3834 Standard for the individual employees?

  • Helps to do the job more satisfactorily
  • Greater job security
  • Higher regard by other people
  • Professional recognition
  • Satisfied employer and customer
  • More rewarding job position
  • Develops team spirit

How important are welding personnel?

A key feature of ISO 3834 is the requirement to ensure that people with welding responsibilities are competent to discharge those responsibilities. This is achieved by incorporation of another standard, namely, ISO 14731 “Welding coordination – Tasks and responsibilities”. The specifying of minimum requirements for personnel dealing with welding coordination and welding inspection personnel.

What is the definition of a manufacturer as per standard?

ISO 3834 defines a manufacturer as a ‘person or organization responsible for the welding production’.

The Standard uses this term to describe any such organisation, including manufacturing organisations supplying welding services, either for new products or for repair and maintenance, as well as others where the application of the requirements of ISO 3834 are relevant.

A manufacturer may be involved in manufacture, fabrication, construction, repair or maintenance.

What are the types of manufacturing organisation that ISO 3834 can be applied to?

Fabrication companies

• Construction companies – on-site work

• Repair and maintenance contractors

• Manufacturers of products

• Welding workshops on sites under the same technical and quality management

• Owners of plant with their own workshop(s)

What are the types of other organisation that ISO 3834 can be applied to?

Asset owners without own workshops, both private and government

• Project management companies

• Design companies

• Consultants

• Government agencies

Those which, though not creating welded product themselves, are specifying or requiring such work from others and are thus involved in weld design, contract development, and review of technical requirements and competencies of subcontractors

How many parts does ISO 3834 have?

  • ISO 3834: 2005 “Quality requirements for fusion welding of metallic materials” consists of 6 parts:
  • ISO 3834-1:2005, Criteria for the selection of the appropriate level of quality requirements
  • ISO 3834-2:2005, Comprehensive quality requirements
  • ISO 3834-3:2005, Standard quality requirements
  • ISO 3834-4:2005, Elementary quality requirements
  • ISO 3834-5:2005, Applicable documentation (not full title)
  • ISO/TR 3834-6:2007, Guidelines on implementing ISO 3834

How does ISO 3834 link in with ISO 9001?

ISO 3834 does not replace ISO 9001 as a quality management system. However, it contains many attributes that will be important for a welding manufacturer, in both workshops and at field installation sites, seeking ISO 9001 certification. Elements of ISO 9001 should be considered when implementing ISO 3834 quality requirements and seeking ISO 3834 certification. The specific complementary elements of ISO 9001 are detailed in ISO 3834.

How do Manufacturers select the Appropriate Part of ISO 3834?

A balanced decision needs to be taken based on the following, related to products & processes:

  • The extent and significance of safety-critical products
  • The complexity of manufacture
  • The range of products manufactured
  • The range of different materials used
  • The extent to which metallurgical problems may occur
  • The extent to which manufacturing imperfections e.g. misalignment, distortion or weld imperfection, affect product performance
  • Service condition (Dynamic loading, fatigue, low/high Temperature, corrosion)
  • The welding processes adopted, their level of sophistication and automation

Suggested Steps for Implementation of ISO 3834 by an Organisation

  • Gap Analysis to identify action areas for  System, training and resources
  • Upgradation of System based on above
  • Personnel Training for competence
  • Assessment of additional Resources if any
  • Internal Audit to close NCR’s
  • Management Review
  • Trial operation to stabilise system
  • Application for Certification to Certification Body

Gap Analysis internally by the Organisation against requirements of ISO 3834 & ISO 14731

  • ISO 9001 systems if existing or desired and compare with the present system.
  • System requirements for applicable part of 3834 (2, 3 or 4) as determined previously and detailed in next three slides.
  • Identify each area as per check list for gaps between required/desired level and actual status recorded.
