Welding Procedure requirements Clause Samples

Welding Procedure requirements. The welding procedure requirements to be described in this sub-section include the following: - Outline of the procedures to be adopted and documents to be submitted to, and accepted by the IO - Definition of the requirements of applicable codes and standards The Supplier shall prepare welding plan, welding design, Welding Procedure Specification, Welding Procedure Qualification, Welder Certificate, etc. - Welding Procedure Specification (WPS): defines the requirements of a WPS, a document providing the welder or operator specific instructions on how to complete a welded joint - Welding Procedure Qualification and Procedure Qualification Record: o Welding Procedure Qualification (WPQ): intended to provide proof of weldability of a metal with a particular process, using the parameters stated in the WPS o Procedure Qualification Report (PQR): a record of the parameters used during the WPQ defining the requirements of applicable codes and standards - Welder Qualification: defines requirements relating to the Welder Qualification (WQ) which is intended to prove welder/welding operator's ability to deposit sound welded metal when using a qualified WPS. As a general rule all the welding activities carried out by the manufacturer shall be supported by: - A weld plan that specifies the location of each welds that identifies each type of welds, and cross- references the supported Welding Procedure Specification (WPS). - The Welding Procedure Specifications that provide the welder or operator specific instructions and conditions for achieving the welding operation. - The Welding Procedure Qualifications (WPQ) providing the proof of the assembly quality. - The Procedure Qualification Records (PQR) which record the results of the test and the parameters used during the Welding Procedure Qualification. - The Welder or Operator Qualification (WQ), which provides the proof of the welder or operator’s ability to execute a particular Welding Procedure Specification. The requirements regarding the weld plan, the WPS, the WPQ, the PQR and the WQ depend on the codes and standards appropriate to the classification classes of the components. These documents will require IO/DA approval prior to the start of any welding activity. Subsequent to the submission and approval by IO/DA of these documents, the supplier shall establish and maintain a list of qualified welders and procedures.
