What is iso 15614?

ISO 15614-1:2017 defines the conditions for the execution of welding procedure tests and the range of qualification for welding procedures for all practical welding operations within the qualification of this document.

What is a WPQR?

Welding Procedure Approval (WPQR) is a certification that covers: the welding method of each source, the material group and the source material, indicating that the material is compatible and according to the project standard in accordance with the ASME or EN Codes made of resources, non-destructive tests and …

What is the main aim of welding procedure qualification?

Welding Procedures are the guidelines used to perform a weld. They are designed to provide a record of the welding variables used and the inspection results obtained during the procedure qualification test.

What is main difference between EN and ASME welding procedures?

ASME B31.1 – EN13941 main differences 1 are for pipe above ground and EN 13941 are for directly buried pipes. ASME B31. 1 cover pressure pipes and other components for heat stations etc.

What is maximum interpass temperature?

Maximum interpass temperatures of 150°C for austenitic stainless steel and nickel-base alloys, and 70°C for aluminum alloys are generally required to prevent hot cracks.

What is WPQR and WPS?

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). A PQR is a record of a test weld performed and tested (more rigorously) to ensure that the procedure will produce a good weld.

How long does a WPQR last?

It provides for a 6 month expiration default but let’s you customize the expiration time-frame by each process.

What is EQT in welding?

A Welding Electrode Qualification Test Is A Process Of Qualifications Of Electrodes By following Process Of Standard. A welding electrode qualification test determines whether the weld filler metal meets specified characteristics for its intended use.

What is AWS and ASME?

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. Contracts may specify one or the other code.

What is API in welding?

For those interested in a career within the welding industry, an American Petroleum Institute (API) welding certification can be a valuable addition to welding training and experience.

What happens if interpass temperature is too high?

High values of interpass temperature tends to decrease the weld metal strength (i.e., ferritic steel) and promote undesired secondary precipitation (in some stainless steels).
