14731 Quality Requirements for Equipment
Welding ([your company acronym])

1.0 Foreword
Welding quality for manufacture of the equipment specified is critical. Welding is a special
process where the final result cannot be categorically verified by testing. The quality of the
welding must be manufactured into the product during manufacture and not solely inspected
into the product. Therefore, welding requires continuous control and the use of specific
procedures. This Standard deals with the quality requirements in welding that are critical for
the contract. In essence, the Supplier shall have:
Systems and processes in place to manage welding operations.
Competent people to undertake key welding tasks and responsibilities.
Facilities and equipment that is able to deliver a quality product per the contract.
It is intended that this Standard will be provided as an attachment with specifications for the
manufacture of welded equipment.
Please note that the standard ISO 3834: 2005 is identical to AS/NZS ISO 3834: 2008.

.04 Requirement for ISO 3834 Compliance

The Supplier shall use and demonstrate that its welding management system complies with
ISO 3834: 2005 Quality Requirements for Fusion Welding of Metallic Materials. Specifically,
the Supplier shall comply with one of the following three; ISO 3834: 2005 Part 2, ISO 3834:
2005 Part 3, or ISO 3834: 2005 Part 4.
Note that the contents of ISO 3834: 2005 Parts 1, 5, and 6 shall be used for reference as
applicable.

.05 Selection of ISO 3834 Level

The final selection of level (ISO 3834 Part 2 Comprehensive, ISO 3834 Part 3 Standard, or
ISO 3834 Part 4 Elementary) will be specified by [your company name]. The Supplier shall
obtain confirmation of the selected quality level prior to the commencement of manufacture.
For selection of quality level, [your company name] will use appropriate engineering
judgement in making a final selection, taking all business, safety and environmental risks into
account for the equipment being manufactured. Table 1 on the next page provides examples
of sensible welding level selections for a number of different equipment groups.
The selection criteria listed in ISO 3834: 2005, Part 1 will be consulted whenever selections
are being made.
If no selection of level is provided by [your company name] then the Comprehensive Quality
Level per ISO 3834 Part 2 shall be used.

.06 Requirement for ISO 14731 Welding Coordination Compliance

As specified in ISO 3834: 2005 Parts 2 and 3 clause 7.3, the Supplier shall coordinate
welding related operations through a RWC having tasks, responsibilities and authority defined
by the Supplier and in accordance with ISO 14731: 2006. For qualifications the of the RWC,
specific reference is made to Annex A of ISO 14731: 2006. The minimum acceptable
qualification for a RWC is an IWS and the RWC is listed on an IIW ANBs database of certified
welding co-ordination personnel. Suitably experienced IWEs or IWTs may also be RWCs .

An IWS acting as a RWC, however, shall contract the expert knowledge of a suitably qualified
and experienced person (eg. IWE or IWT), in welding technology areas beyond the scope of
his/her technical expertise.

.07 Welding Procedure and Welder Qualification

ISO 3834: 2005 makes reference to other ISO standards with respect to welding procedure
qualification and welder qualification(1). For the equipment specified the requirements and
standards as referenced in the equipment specification shall take precedence.
(1)
Welder qualification in this Section relates to the requirement of design codes that
welding personnel prove competence to perform specific welds using an appropriate
test.

.08 Post Weld Heat Treatment

ISO 3834: 2005 makes reference to other ISO standards with respect to post weld heat
treatment. For the equipment specified, requirements and standards as referenced in the
equipment specification shall take precedence.

.09 Inspection and Testing

ISO 3834: 2005 makes reference to other ISO standards with respect to inspection and
testing. For the equipment specified, requirements and standards as referenced in the
equipment specification shall take precedence.
The welding inspection personnel shall be qualified and certified to the appropriate WTIA
Certification Programme for welding inspection personnel, ie,
WTIA Certified Comprehensive Welding Inspector (CCWI)
WTIA Certified Senior Welding Inspector (CSWI)
WTIA Certified Welding Inspector (CWI)

Note: The WTIA certification programme is based upon the IIW qualification programme.
Certification through other national programmes based on the IIW qualification programme
can be acceptable subject to approval by [Insert your company name here]. Personnel

holding certification from other national programmes not based on the IIW qualification
programme can also contact WTIA to obtain information on alternative routes to obtain WTIA
certification.

Detailed information on the above can be obtained by reference to the WTIA Q&C Board
(info@wtia.com.au).

.010Pre-Qualification to ISO 3834

Before contract commencement the Supplier will be pre-qualified by [your company name] to
supply the equipment specified. For this pre-qualification, the Supplier shall make
manufacturing facilities available so an assessment can be made of the capability of meeting
all requirements of this Standard and providing the specified product on time per the contract
schedule. Pre-qualification will be carried out by [your company name] using the services of
an audit team or person acceptable to [your company name]. In most cases, this will be done
using the services of the WTIA or its overseas affiliates as appropriate. Pre-qualification will
involve a combination of questionnaire, document audit, and quality/technical audit of the
facilities that will be used for manufacture of the specified equipment.

.011 Certification and Documentation of ISO 3834 Quality System

Certification to IIW MCS ISO 3834 provides independent recognition of the Suppliers
capability and competence to manage its welding activities and demonstrate its commitment
to deliver quality welded products. Certification is available via the IIW and its ANBCC in
Australia, namely the WTIA (contact info@wtia.com.au for further information).

Unless certification to IIW MCS ISO 3834 is held [your company name] reserves the right to
conduct an in-depth audit of the suppliers quality system prior to the decision to purchase any
of the equipment identified in Table 1 of this document.

.012Technical Assistance
The WTIA has indicated a commitment to assist Suppliers with deployment of ISO 3834:
2005. To this end, a TGN has been developed by the WTIA with the assistance of industry.
