To be referenced as a supporting document for an SWPS, a PQR received from an industry or government agency must be qualified and documented in accordance with one of the nationally recognized codes or specifications such as AWS D1. It is the policy of the AWS B2 Committee that the range of conditions and variables listed for an SWPS be more restrictive than permitted by application of the full range of conditions and variables allowed by the B2.
The purpose of this policy is to restrict the WPS to a high probability of successful application by all users. In judging the extent of such restriction, the Committee is guided by the number and scope of the supporting PQRs, including the specific material, thickness and value for each welding variable used for the development of the PQR, and by known fabrication experience.
The minimum number of supporting PQRs required by the Committee is two, but is usually in the range of two to fifty, the specific minimum number being a Committee decision for each SWPS.

Because of huge number of variables involved, the knowledge of the welding engineer and the skill of the welder need to be validated by a series of tests.
A WPS is a document that describes how welding is to be carried out in production. Its purpose is to aid the planning and quality control of the welding operation. They are recommended for all welding operations and most application codes and standards make them mandatory. A PQR is required when it is necessary to demonstrate that your company has the ability to produce welds possessing the correct mechanical and metallurgical properties.
A welding procedure must be qualified in accordance with the requirements of an appropriate welding procedure standard, such as ASME Sec IX, as follows:. Sufficient details to enable any competent person to apply the information and produce a weld of acceptable quality. The amount of detail and level of controls specified on a WPS is dependant on the application and criticality of the joint to be welded.
For most applications the information required is generally similar to that recorded on a Procedure Qualification Record PQRexcept that ranges are usually permitted on thicknesses, diameters, welding current, materials, joint types etc.
If a WPS is used in conjunction with an approved procedure qualification record PQR then the ranges stated should be in accordance with the approval ranges permitted by the PQR. However careful consideration should be given to the ranges specified to ensure they are achievable, so that these ranges represent good welding practice.
Some codes, such as AWS D1. It is not necessary to prepare a PQR in such cases. However, the pre-qualified WPS have a specified range of parameters under which the weld must be produced. When the use of SWPSs is permitted by referencing code section, your company does not have to perform one or more procedure qualification tests.
Once the procedure is approved it is necessary to demonstrate that all your welders working to it have the required knowledge and skill to put down a clean sound weld. If the welder has satisfactorily completed the procedure test then he is automatically approved but each additional welder must be approved by completing an approval test to an appropriate standard such as ASME Sec IX as follows:. In general welds must show a neat workman like appearance. The root must be fully fused along the entire length of the weld, the profile of the cap should blend in smoothly with the parent material and the weld should be significantly free from imperfections.
Reference should be made to the acceptance standard for precise details. In addition to the above, you may require independent inspection of the welds by the following qualified personnel:. Third Party Inspections. The cart is empty. What information should they include? What is a Prequalified WPS?

How much do I need to know before taking this course?For a given application, the main way of ensuring adequate weld quality is to specify the procedure and the skill level of the welding operator.
Here, the alternative routes for welding procedure approval are described together with the requirements for welder or welding operator approval. The key document is the Welding Procedure Specification WPS which details the welding variables to be used to ensure a welded joint will achieve the specified levels of weld quality and mechanical properties. In both the European and ASME standards, there are a number of 'essential variables' specified which, if changed, may affect either weld quality or mechanical properties.
Therefore, a change in any of the essentials will invalidate the welding procedure and will require a new approval test to be carried out.
The essential variables are detailed in the relevant specification but include material type, welding process, thickness range and sometimes welding position. The most common method of gaining approval is to carry out an approval test as described in BS EN ISO steels and aluminium and its alloys.
The manufacturer initially drafts a preliminary welding procedure pWPS which is used by one of the manufacturer's competent welders to prove that it is capable of producing a welded joint to the specified levels of weld quality and mechanical properties.
The welding procedure approval record WPAR is a record of this weld. But alternative methods have certain limits of application regarding, for example, welding processes, materials and consumables as specified in the appropriate application standard or contract agreement.
The welding procedure test method of approval is often a mandatory requirement of the Application Standard. If not, the contracting parties can agree to use one of the alternative methods. For example, a welding procedure specification can be approved in accordance with the requirements of BS EN ISO previous experience on condition that the manufacturer can prove, with appropriate documentation, that the type of joint has previously been welded satisfactorily.
The welder approval test is carried out to demonstrate that the welder has the necessary skill to produce a satisfactory weld under the conditions used in production as detailed in the approved WPS or Work Instruction.
As a general rule, the test piece approves the welder not only for the conditions used in the test but also for all joints which are considered easier to weld. As the welder's approval test is carried out on a test piece which is representative of the joint to be welded, it is independent of the type of construction. The precise conditions, called 'essential variables', must be specified in the approval test, eg material type, welding process, joint type, dimensions and welding position.
The extent of approval is not necessarily restricted to the conditions used for the test but covers a group of similar materials or a range of situations which are considered easier to weld. It is important to note that a number of Amendments and Corrigenda have now been issued which affect the range of approval see list of Relevant Standards.
The welder approval certificate remains valid subject to the requirements of the application standard. American standards have similar requirements although the extent of approval of the welding variables are different to those of BS EN ISO In clarifying the term 'welding operator', personnel who are using the equipment loading and unloading robotic equipment or operating a resistance welding machine do not require approval.
As specified in BS EN ISO"Welding personnel — Qualification testing of welding operators and weld setters for mechanized and automatic welding of metallic materials" can be based on:. It should be noted that the methods must be supplemented by a functional test appropriate to the welding unit.
However, a test of knowledge relating to welding technology which is the equivalent of 'Job knowledge for welders' in BS EN ISO is recommended but not mandatory.
The essential variables are different to those in welder approval. Part 1 Arc and gas welding of steels and arc welding of nickel and nickel alloys. Part 2: Aluminium and aluminium alloys.

Welding procedure.A Welding Procedure Specification WPS is the formal written document describing welding procedures, which provides direction to the welder or welding operators for making sound and quality production welds as per the code requirements. The purpose of the document is to guide welders to the accepted procedures so that repeatable and trusted welding techniques are used.
A WPS is developed for each material alloy and for each welding type used. A PQR is a record of a test weld performed and tested more rigorously to ensure that the procedure will produce a good weld.
Individual welders are certified with a qualification test documented in a Welder Qualification Test Record WQTR that shows they have the understanding and demonstrated ability to work within the specified WPS. According to the American Welding Society AWSa WPS provides in detail the required welding variables for specific application to assure repeatability by properly trained welders. The AWS defines welding PQR as a record of welding variables used to produce an acceptable test weldment and the results of tests conducted on the weldment to qualify a Welding Procedure Specification.
For steel construction civil engineering structures AWS D1. It specifies either a pre-qualification option chapter 3 or a qualification option chapter 4 for approval of welding processes. The American Society of Mechanical Engineers ASME similarly defines a WPS as a written document that provides direction to the welder or welding operator for making production welds in accordance with Code requirements.
The record also contains the test results of the tested specimens. A record of the procedure qualification test and the results must be documented on a procedure qualification record PQR. EN ISO defines a WPS as "A document that has been qualified by one of the methods described in clause 6 and provides the required variables of the welding procedure to ensure repeatability during production welding".
The same standard defines a Welding Procedure Qualification Record WPQR as "Record comprising all necessary data needed for qualification of a preliminary welding procedure specification". In the oil and gas pipeline sector, the American Petroleum Institute API standard is used almost exclusively worldwide. From Wikipedia, the free encyclopedia.
The purpose of the welder qualification test procedure is to follow a standardised and reliable process for all welders and workers seeking to meet this specific welding requirement. This procedure also typically serves as the record of competence, as a supervisor or responsible person documents the results of the qualification test procedure as it is being conducted.

Difference Between WPS and PQR
WPS further explains the rules and details of the test and how the pieces should be assembled. Simply put, a WPS is like a blueprint for welders to produce the same quality of welded product over and over again. Product Qualification Record is another type of document that also refers to welding. In addition, it also includes some observations or other matters regarding welding procedures and specific tests like tensile tests and guided bend tests.
It may also show the visual inspection and fillet weld test results. The PQR is prepared by a qualified or licensed individual and submitted to the people concerned. The inspector will then endorse the company and its product to the industry and market. Cite Celine. June 7, Thanks for these details. Name required. Email required.
