ASME and AWS welding codes—Similarities and differences
Some don't, and those usually reference existing codes and standards for their manufacturing, fabrication and construction projects. In the United States, these organizations are usually independent organizations from private industry, but in many countries they are government agencies. The listing below, which is not all-inclusive, provides examples of some of the standards bodies that are commonly used by NDT personnel. Below the name and web address of each standards body is a brief description of that body. These are examples of some of the NDT-related codes, standards or specifications published by that organization. All of the organizations listed here use industry subject-matter experts and a consensus process in the development of their codes and standards. ASTM International formerly the American Society for Testing and Materials is one of the largest voluntary standards development organizations in the world, providing technical standards for materials, products, systems and services.
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.
Commonly Used Welding Codes
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:. Our welding engineers are qualified to work according to the main international welding standards, many of them are involved in the standardisation committees and their skills have often proven crucial in providing clarification on the intent of clauses within welding standards.

Codes and Standard Bodies
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 International Boiler and Pressure Vessel Code establishes rules of safety governing the design, fabrication, and inspection of boilers and pressure vessels, and nuclear power plant components during construction.
Беккер понимал, что в данный момент ничего не может предпринять. Ему оставалось только стоять на коленях на холодном каменном полу огромного собора. Старик утратил к нему всякий интерес, прихожане встали и запели гимн. Ноги у него свело судорогой. Хорошо бы их вытянуть.
Сьюзан, увидев, что дело пошло, попыталась помочь Стратмору. Дверь приоткрылась на несколько сантиметров. Они держали ее что было сил, но сопротивление оказалось чересчур сильным и створки снова сомкнулись. - Подождите, - сказала Сьюзан, меняя позицию и придвигаясь ближе. - Хорошо, теперь давайте.
