What is a weld log?
Traditionally, operators have used a “weld log”- a paper sheet with fields for data points on each weld. This concept of a worksheet filled with fields on a repetitive, manual task is common across many other documents in a production environment, not only the welding industry.
What is shown in the sketch on a WPS?
A sketch of the joint configuration is required which should include the basic dimensions of the weld preparation. Some indication of the run sequence is also beneficial, particularly if the correct sequence is essential to ensure the properties of the weld are maintained.
What is WPS in welding 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 difference between WPS and PQR?
In case you are wondering, a WPS stands for ‘welding procedure specification’ and a PQR is ‘procedure specification record’. A WPS and PQR are mandatory documents when welds need to comply to a standard. The PQR is a standard document, but the people who use it may not necessarily come from the same background.
What is a PQR 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 is the correct way to show weld all the way around?
Weld All-Around and Field Weld Symbols Welds extending completely around a joint are indicated by the weld-all-around symbol (fig. 3-7). Welds that are completely around a joint that includes more than one type of weld, indicated by a combination weld symbol, are also depicted by the weld-all-around symbol.
What are Weld maps and Weld logs?
Weld maps illustrate the location of each weld , which is labeled with a unique identification number, as well as the part number of every component. A weld log contains all information that relates to each weld, including project and job numbers.
What is Weld map?
Weld Map: A document which includes but not limited to a Sketch of the equipment locating all the welds along with a table with all the details (Material, thickness, welding process, WPS, PQR etc…) required for getting customer/client/TPI approval.
What is welding map?
What is the Welding Map? The welding map is the equipment sketch which identifies the welding seams and indicates what welding procedure specification (WPS) shall be used for that particular welding seam. The welding procedure specifications (WPS’s) are provided by the manufacturer to the customer for approval.
