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.

ASME and AWS welding codesâSimilarities and differences ASME materials are listed by P and S numbers. There are very few restrictions as to size and strength of material. This is a reason for qualifying welders and procedures to the ASME Section IX when possible. Welding codes are intended to improve skills, processes, materials, and equipment. They are important in achieving maximum quality and efficiency.

- In between the euphotic and the bathyal zone is the twilight zone, an area that still receives some sunlight, but not enough for plants to grow. The bathyal zone (aka midnight) is the middle zone that has no light. Many zooplankton and smaller fish live here.he euphotic zone is from the surface of the ocean down 200 meters. This zone is also sometimes called the sunlight zone because there is enough sunlight to have photosynthesis. This zone has the highest levels of sunlight, photosynthesis, and dissolved oxygen. Many large predatory fish live here.

Difference Between WPS and PQR However, unlike WPS, the PQR document’s purpose is to serve as a checklist or record of compliance regarding the standard requirements of an appropriate welding procedure. The PQR form covers all the welding parameters in the WPS document.

Welding Procedure Specification 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. Specific codes and/or engineering societies are often the driving force behind the development of a company's WPS. A WPS is supported by a Procedure Qualification Record (PQR or WPQR).

How to Write a Technical Specification A technical specification is a document that defines a set of requirements that a product or assembly must meet or exceed. A product or assembly that does not meet all of the specifically expressed requirements does not meet the specification, and often is referred to as being out of specification or out of spec..

Welding Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing fusion, which is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal.as tungsten arc welding (GTAW), or tungsten inert gas (TIG) welding, is a manual welding process that uses a nonconsumable tungsten electrode, an inert or semi-inert gas mixture, and a separate filler material.

Arc welding Duty cycle is a welding equipment specification which defines the number of minutes, within a 10 minute period, during which a given welder can safely produce a particular welding current. For example, a 150 amp. welder with a 30% duty cycle must be rested for at least 7 minutes after 3 minutes of continuous welding.
