Full text of ” IS In this adopted standard, some terminology and conventions are, however, not identical to those used in Indian Standards. Attention is especially drawn to the 9956- In this adopted standard, reference appears to certain International Standards for which Indian Standards also exist.

The 99556-2 Indian Standards which are to be substituted in their place are listed below along with their degree of equivalence for the editions indicated: International Standard ISO Part 1 Guidelines for selection and use IS Part 3: Part 3 Standards quality requirements IS Part 4: Part 4 Elementary quality requirements IS Part 1: Part 1 Fusion welding of steel IS Part 2: This part of ISO is appropriate when demon- stration of a manufacturer’s capability to produce welding constructions and to fulfill specified quality requirements, are specified in one or more of the fol- lowing: The requirements contained within this part of ISO may be adopted in full or may be selectively deleted by the manufacturer if not ido to the construction concerned.

They provide a flexible framework for the control of welding in the following cases: Case 1 To provide specific requirements for fusion welding in contracts which require the manufacturer to have a quality system in accordance with ISO or ISO Case 2 To provide specific requirements for fusion welding in contracts which require the manufacturer to have a quality system other than ISO or ISO Cases To provide specific requirements for fusion welding as guidance to oso manufacturer developing a quality system.

Case 4 To provide specific requirements for references in application standards which uses fusion welding as part of its requirements or in a contract between rel- evant parties. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO are encouraged to investigate the possibility of applying the most recent editions of the IS Part 2: Guidelines for selection and use.

Aluminium and 995-2 alloys. Welding procedure specification for arc welding. Welding procedure tests for io arc welding of steels. Welding procedure tests for the arc welding of alu- minium and its alloys. This is to ensure that all information necessary to carry out the fabrication operations is available oso to the ixo of the work.


The manufacturer shall affirm his capability uso meet all welding contract requirements and ensure adequate planning of all quality related activities. Contract review is carried out by the manufacturer to verify that the contract is within his capability to per- form, that sufficient resources are available to achieve delivery schedules and that documentation is clear and unambiguous.

The isi should ensure any variations between the contract and previous tender documentation are identified and the pur- chaser notified of any programme, cost or engineering changes that may result.

The items in 4. It shall be ensured that all relevant information has been sup- plied by the purchaser. When a contract does not exist, e.

The information to be provided by the manufacturer to the sub-contractor shall 996-2 all relevant data from the contract review see 4.

Additional requirements may need to be specified if the design of a structure is to be sub- contracted. All records of approval shall be maintained up to date.

Such persons having responsibility for quality activities shall have sufficient authority to enable any necessary action to be taken. The duties, interrelationships and limits of responsibility of such persons should be clearly de- fined. The subcontractor shall provide such records and documentation of his work as may be specified by the manufacturer.

Any subcontractor shall work under the order and re- sponsibility of the manufacturer and fully comply with the relevant requirements jso this part of ISO The manufacturer shall ensure that the subcontractor can comply with the quality requirements of the con- tract. IS Part 2: This list shall identify items of major equipment, essential for an evaluation of workshop capacity and capability. This includes, for example: Other equipment only needs to be specified by ap- proximate total numbers ixo cover each general type e.

Approval of welding and heating equip- ment is not normally required unless specified in the contract.

The tests shall verify the correct function of the equipment. The tests shall be carried out in ac- cordance with appropriate standards, whenever rel- evant.

Records shall be maintained of such tests. The plan shall ensure maintenance checks of those items in the equipment which controls variables listed in the relevant welding procedure specifications. The plans may be limited to those items which are essential for assuring the quality of the welded construction. Examples of those items are: Defective equipment shall not be used. This shall include at least: The method of approval shall be in accord- ance with the relevant application standards or as stated in the contract.

The procedures shall be in accordance with the sup- plier’s recommendations. Identification shall be maintained during storage.

Alternatively, he may use dedicated work instructions. Such dedicated work in- structions shall be prepared from an approved weld- ing procedure specification and do not require separate approval see ISO The manufacturer shall be fully responsible for the specification and the performance of any post-weld heat treatment.


The procedure iiso be compatible with the parent metal, welded joint, construction etc. A record of the heat treat- ment shall be made during the process. The record shall demonstrate that the specification has been fol- lowed and shall be traceable to the particular heat treatment operation. The manufacturer may carry out additional tests without restriction. Reporting of such tests is not re- quired. When repair or rectification is carried out, “the items shall be re-inspected, tested and examined in accord- ance with the original requirements.

ISO 9956-2:1995

Measures shall also be implemented to ensure that conditions ad- verse to quality of the welded construction are promptly identified and corrected. All equipment used to assess the 99566-2 of the welded construction shall be suitably controlled and shall be calibrated at specified intervals. Documented systems to ensure identification 956-2 traceability of welding operations should include, when necessary: Quality records shall be retained for a minimum period of 5 years in the absence of any other specified re- quirements.

In reporting the results of a test or analysis, made in accordance with this standard, if the final value, observed or calculated, is to be rounded off, it shall be done in accordance with IS 2: But eau of Indian Standards BIS is a statutory institution establisiied under the Bureau 99556-2 Indian Standards Act, to promote harmonious development of the activities of standardization, marking and quality certification of goods and attending iao connected matters in the country.
