TWI's welding engineers have extensive experience operating to international codes, standards, regulations and specifications from procedure qualification for original fabrication to quality control and quality assurance during welding to repair process development in all industry sectors. Our welding engineers can provide an expert opinion on all the major welding and fabrication standards:.

American Welding Society Publication s. The American Welding Society holds the copyright for these Standards. Please consult the American Welding Society for updates to these standards.

All sections contain welding specifications, however most relevant information is contained in the following:. API maintains over standards covering the oil and gas field. Standards Australia is the body responsible for the development, maintenance and publication of Australian Standards. International Organization for Standardization ISO has developed over standards and over new standards are published every year. The European Committee for Standardization CEN had issued numerous standards covering welding processes, which unified and replaced former national standards. From Wikipedia, the free encyclopedia.

To be referenced as a supporting document for an SWPS, a PQR received from an industry or government agency must be qualified and documented in accordance with one of the nationally recognized codes or specifications such as AWS D1. It is the policy of the AWS B2 Committee that the range of conditions and variables listed for an SWPS be more restrictive than permitted by application of the full range of conditions and variables allowed by the B2. The purpose of this policy is to restrict the WPS to a high probability of successful application by all users. In judging the extent of such restriction, the Committee is guided by the number and scope of the supporting PQRs, including the specific material, thickness and value for each welding variable used for the development of the PQR, and by known fabrication experience. The minimum number of supporting PQRs required by the Committee is two, but is usually in the range of two to fifty, the specific minimum number being a Committee decision for each SWPS.

It is accessible via complimentary electronic distribution. This document provides the AWS base metal grouping for welding procedure and performance qualification and is identical to the base metal grouping annex found in the latest version of AWS B2. Print copies are available for purchase at pubs. Use of Forms For joint details on the WPS, a sketch or a reference to the applicable prequalified joint detail may be used e. The WPS forms contain lines for inclusion of information that may not be required by the code; these lines need not be completed in order to comply with code requirements.

Four groups set the foundation for the codes. Each group sets and adapts codes that pertain to their area of interest. The most commonly used codes are from the AWS D1. AWS is for both welder and welding procedure qualification including inspection, erection and fabrication. Contracts may specific one or the other code.

All new standard welding procedure qualifications are to be carried out in accordance with this document from the date of its issue. However, this document does not invalidate previous standard welding procedure qualifications made to former standards, specifications or previous editions of this document. Check out our FAQs.

Он зря мне доверился. Ключ стоит в сотни раз больше того, что он платит мне за его хранение. - Извините, но ваш ключ сам по себе ничего не стоит. Как только Танкадо узнает о том, что вы сделали, он опубликует свою копию, и рынок рухнет. - Вы получите оба экземпляра, - прозвучал голос.  - Мой и мистера Танкадо. Нуматака закрыл трубку ладонью и громко засмеялся.

 - Я думаю, - начала она, -что я только… -но слова застряли у нее в горле. Она побледнела. - Что с тобой? - удивленно спросил Хейл.

Стеклянный купол словно наполнился то и дело вспыхивающими огнями и бурлящими клубами пара. Бринкерхофф стоял точно завороженный и, не в силах унять дрожь, стукался лбом о стекло. Затем, охваченный паникой, помчался к двери. - Директор. Директор! - кричал .
