How do you write a welding procedure specification?

All the basic information about the welding procedure:

1. Name of the company and person who developed it.
2. Specification number and date.
3. Most WPS will be backed on a PQR (Procedure Qualification Record), you should refer to it in order to make it easy to trace the document back.
4. Number and date of the last revision.

What is WPS form?

The Full Form Of WPS is a Wi-Fi Protected Setup. WPS is the network security standard that helps to create a protected and secure wireless home network.

What is welding procedure specification PDF?

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 . A WPS is supported by a Procedure Qualification Record (PQR or WPQR).

What is a PQR in welding?

The procedures for creating and testing the sample welds, as well as the final results, are documented on a Procedure Qualification Record, or PQR. In short, a PQR serves as evidence that a given WPS can, in fact, be used to produce an acceptable weld.

What PQR means?

Procedure Qualification Record
The procedures for creating and testing the sample welds, as well as the final results, are documented on a Procedure Qualification Record, or PQR. In short, a PQR serves as evidence that a given WPS can, in fact, be used to produce an acceptable weld.

What PQR stands for?

The procedures for creating and testing the sample welds, as well as the final results, are documented on a Procedure Qualification Record, or PQR.

What is the purpose of PQR?

A Procedure Qualification Record (PQR) is the record of the actual weld test parameters used.It is the founding document as far as procedures are concerned and is used to produce welding procedure specification sheets (WPS) for production welds. It is company dependent and never expires.

What are the requirements to write welding procedures?

Procedure number,

Reference to the specific engineering drawing and to the detailed operation covered,

Standard designation and condition of materials,thickness,

Sketch describing form of joint with dimensions and tolerances,

Need for preheating or post weld heat treatment,

What is the a number in Welding Procedure Specification?

The A-Number: The A-Number is a calculated value based on a combination of the chemical composition of the weld filler metal (which may be found in ASME Section II

Table QW-442:

What is Standard Welding Procedure?

Answer Wiki. “Welding Procedure Specifications is a form that contains details of welding groove, welding method to be employed, electrode and/or welding rod type and diameter, current, voltage, welding position, welding run number and similar information prepared in accordance with its codes relevant Project standard (ASME and/or EN Standards).

What is the Welding Procedure Specification (WPS)?

Create a Welder Procedure Specification (WPS) – a ‘technique’ card that documents how to produce a weld.

Carry out non-destructive testing and destructive testing on the weld test piece produced under the WPS in our laboratories.

Verify the weld test piece meets the applicable codes or standards
