What does WPQR mean in welding?

Welding Procedure Qualification Record (WPQR) A WPQR is a company-specific qualification that proves that the holding company possesses the technical welding knowledge necessary to perform metal joining work.

What is the difference between WPS and WPQR?

WPS serves as a blueprint for a written instruction or guide on how to create a welded product based on a certain standard and quality. Meanwhile, PQR is a document that checks whether the standard is being followed by inspecting and answering the document regarding specific areas and tests.

What is WPS PQR and WPQ?

Here's the translation. WPS – Welding Procedure Specifications. PQR – Procedure Qualification Records, and. WQT / WPQ – Welder Qualification Test / Welder Performance Qualifications.

What is WPS & 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. Both documents are closely related, but they are not the same.

What is the purpose of WPQR?

A record of welding variables used to produce an acceptable test weldment and the results of tests con-ducted on the weldment to qualify a welding procedure specification.

What are the 5 essentials of welding?

WELDING PROCEDURES
  • 5 essentials for proper welding procedures.
  • 1) CORRECT ELECTRODE SIZE.
  • 2) CORRECT CURRENT.
  • 3) CORRECT ARC LENGTH or VOLTAGE.
  • 4) CORRECT TRAVEL SPEED.
  • 5) CORRECT ELECTRODE ANGLE.
  • 8 FACTORS to consider in selecting arc welding electrodes.

Is it possible to qualify welder during WPQ?

The WPQ record indicates the ability of the welder or welding operator to deposit sound weld metal. The WPQ can be qualified by either radiography or ultrasonic testing; alternatively it can also be qualified by mechanical testing.

What is WPS quality?

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 developed for each material alloy and for each welding type used.

What comes first PQR and WPS?

PQR contains the observations prepared from the test conducted on the manufactured products. WPS is used before the product is to be welded. PQR is used after the product has been welded and the tests have been completed.

Why you need a WPS?

Why you need a WPS A Welding Procedure Specification is essential for every welding company to have because it maintains quality standards across every weld. It isn't just a nice guide to follow. Under various Australian and international standards (eg. ISO 15612, ISO 15609), a WPS is required to ensure a stable weld.

What is G in welding?

It involves welding on the top side of the joint. In this position, the molten metal is drawn downward into the joint. The result is a faster and easier weld. In 1G and 1F, the number 1 refers to the flat position, while the letter G stands for a groove weld and letter F stands for a fillet weld.

What is difference between AWS and ASME code?

The difference between ASME and AWS is that ASME is for welding procedure and welder qualification. AWS is for both welder and welding procedure qualification including inspection, erection and fabrication.

What are the 4 types of welding process?

There are four main types of welding. MIG – Gas Metal Arc Welding (GMAW), TIG – Gas Tungsten Arc Welding (GTAW), Stick – Shielded Metal Arc Welding (SMAW) and Flux-cored – Flux-cored Arc Welding (FCAW).

Does welding melt metal?

As opposed to brazing and soldering, which do not melt the base metal, welding is a high heat process which melts the base material. Typically with the addition of a filler material. ... Pressure can also be used to produce a weld, either alongside the heat or by itself.

What is WPQ?

A Welder Performance Qualification (WPQ) is a test certificate that shows whether a welder possesses the necessary experience and knowledge to perform the specifications of a particular weld procedure.

What is WQTR?

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.

Why WPS is required?

Why you need a WPS A Welding Procedure Specification is essential for every welding company to have because it maintains quality standards across every weld. ... ISO 15612, ISO 15609), a WPS is required to ensure a stable weld.

What does 6010 mean?

The "60" in 6010 means 60,000 pounds' tensile strength (the ability to resist being pulled apart) per square inch. The "1" means it can be run in any position—flat, horizontal, vertical, or overhead.

Should WPS be on or off?

WPS is a great example of the trade-off between convenience and security. ... This is why we disable WPS. Once disabled, you'll need to use the conventional password method to add additional devices to your wi-fi network (less convenient) but your router will no longer be vulnerable to a WPS attack (more secure).
