What is difference between AWS and ASME?

What is difference between 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.

What is the main difference between EN and ASME welding procedure?

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 does ASME IX cover?

ASME section IX is a part of the ASME boiler pressure vessel code that contains the rules for qualifying welding procedures and welders. It is also used to qualify welders and procedures for welding to ASME B31.

How long does a AWS D1 1 certification last?

six months
AWS Certification remains valid as long as you submit your Certification Maintenance Form every six months as required by the Code of Acceptance that governs your test.

What is the difference between PQR and WPS?

WPS is welding procedure specification whereas PQR is procedure specification record. These are some of the significant and mandatory documents especially to ensure that the welds comply with the rules.

How do I choose 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 ASME BPVC Section IX?

“Section IX of the ASME Boiler and Pressure Vessel Code relates to the qualification of welders, welding operators, brazers, and brazing operators, and the procedures that they employ in welding and brazing. . . “ API 1104 Welding of Pipelines and Related Facilities . .

What is the latest edition of ASME Section IX?

BPVC-IX – 2021.

Does a AWS D1 1 expire?

A WELDING CERTIFICATION IS EFFECTIVE INDEFINITELY According to American Welding Society AWS D1. 1, Clause 4.2. 3.1, a welder’s qualification is effective indefinitely, AS-LONG-AS, that welder does not go more than six months without using that process.

What is the latest AWS D1 1?

AWS D1. 1:2020 contains the requirements for fabricating and erecting welded steel structures. The AWS D1. 1:2020 code also includes information pertinent to its stipulation in contract documents, and it details provisions specific to the responsibilities of the engineer, contractor, and inspector.

Why PQR is required?

This initial procedure is used to create a series of welds which are then mechanically tested to ensure they meet all applicable requirements. In short, a PQR serves as evidence that a given WPS can, in fact, be used to produce an acceptable weld.

What’s the difference between ASME and AWS D1.1?

In the case of ASME, those rules are contained in Section IX of the Boiler and Pressure Vessel Code, and are intended PRIMARILY for boilers, pressure and atmospheric vessels and pressure piping. AWS has issued the Standard D1.1 “AWS Structural Welding Code. Steel”, which is intended PRIMARILY, as the name says, for structural steel.

Can a welder qualify for AWS D1.1 Section IX?

If you qualified your welders to ASME SEction IX, they don’t necessarily meet AWS D1.1. Your ASME WPSs will be lacking as well. Some of the essential variables listed by AWS D1.1 may not be addressed by your ASME procedures.

Can you write papers for AWS D1.1 and ASME IX?

Look for the range of variables that can be used in both codes and write up the paperwork after testing within those ranges. If a ONE test is given in accordance with ASME Sec IX AND AWS D1.1 papers can be prepared for both.

What kind of testing is required for AWS D1.1?

The procedure qualification record (PQR) is a record of test results for the welds made in accordance with the WPS. Destructive testing (tensile pulls, bends, etc.) is required for PQRs in all codes. AWS D1.1 also requires nondestructive testing for procedure qualification. ASME Section IX does not.
