Welder Certification
Welder certification, (also known as welder qualification) is a process which examines and documents a welder's capability to create welds of acceptable quality following a well defined welding procedure. Method Welder certification is based on specially designed tests to determine a welder's skill and ability to deposit sound weld metal. The main part of the welder's test consists of welding one or more test coupons which are then examined using non-destructive and destructive methods. The extent of certification is described by a number of variables, which include the specific welding process, type of deposited metal, thickness, joint design, position, backing, and others. Most often, the test is conducted in accordance with a particular code. Depending on product requirements the test can be administered under the auspices of a national or international organization, such as the American Welding Society (AWS), or American Society of Mechanical Engineers (ASME), but manufactur ...

Welder
In a broad sense, a welder is anyone, amateur or professional, who uses welding equipment, perhaps especially one who uses such equipment fairly often. In a narrower sense, a welder is a tradesperson who specializes in fusing materials together. The term welder refers to the operator, the machine is referred to as the welding power supply. The materials to be joined can be metals (such as steel, aluminum, brass, stainless steel etc.) or varieties of plastic or polymer. Welders typically have to have good dexterity and attention to detail, as well as technical knowledge about the materials being joined and best practices in the field. Safety issues Welding, without the proper precautions appropriate for the process, can be a dangerous and unhealthy practice. However, with the use of new technology and proper protection, the risks of injury and death associated with welding can be greatly reduced. Because many common welding procedures involve an open electric arc or a flame, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Welding Inspector
Weld quality assurance is the use of technological methods and actions to test or assure the quality of welds, and secondarily to confirm the presence, location and coverage of welds. In manufacturing, welds are used to join two or more metal surfaces. Because these connections may encounter loads and fatigue during product lifetime, there is a chance they may fail if not created to proper specification. Weld testing and analysis Methods of weld testing and analysis are used to assure the quality and correctness of the weld after it is completed. This term generally refers to testing and analysis focused on the quality and strength of the weld, but may refer to technological actions to check for the presence, position and extent of welds. These are divided into destructive and non-destructive methods. A few examples of destructive testing include macro etch testing, fillet-weld break tests, transverse tension tests, and guided bend tests.http://www.esabna.com/us/en/education/kno ...

Welding Procedure Specification
Welding is a fabrication process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing fusion. Welding is distinct from lower temperature techniques such as brazing and soldering, which do not melt the base metal (parent metal). In addition to melting the base metal, a filler material is typically added to the joint to form a pool of molten material (the weld pool) that cools to form a joint that, based on weld configuration (butt, full penetration, fillet, etc.), can be stronger than the base material. Pressure may also be used in conjunction with heat or by itself to produce a weld. Welding also requires a form of shield to protect the filler metals or melted metals from being contaminated or oxidized. Many different energy sources can be used for welding, including a gas flame (chemical), an electric arc (electrical), a laser, an electron beam, friction, and ultrasound. While often an industr ...

Accredited
Accreditation is the independent, third-party evaluation of a conformity assessment body (such as certification body, inspection body or laboratory) against recognised standards, conveying formal demonstration of its impartiality and competence to carry out specific conformity assessment tasks (such as certification, inspection and testing). Accreditation bodies are established in many economies with the primary purpose of ensuring that conformity assessment bodies are subject to oversight by an authoritative body. Accreditation bodies, that have been peer evaluated as competent, sign regional and international arrangements to demonstrate their competence. These accreditation bodies then assess and accredit conformity assessment bodies to the relevant standards. An authoritative body that performs accreditation is called an 'accreditation body'. The International Accreditation Forum (IAF) and International Laboratory Accreditation Cooperation (ILAC) provide international recognitio ...

Personnel Certification Body
{{unsourced, date=March 2017 A Personnel Certification Body is an organization that awards credentials to individuals meeting specific competence requirements relating to a profession, an occupation, a job or a portion of a job. A personnel certification body develops criteria against which an individual needs to demonstrate competencies and ensures that these criteria are held by applicants before certifying them. Most personnel certification bodies offer professional certification if an individual meets requirements such as a minimum number of years of related working experience, minimum education level and having passed a certification exam or equivalent. Many personnel certification bodies are accredited by accrediting bodies to the ISO/IEC 17024 standard, which was designed to harmonize the personnel certification process worldwide. Most are not. Accreditation means having gone through a validation process or ''assessment'' from a national accreditation body such as the Amer ...

Notified Body
A notified body, in the European Union, is an organisation that has been designated by a member state to assess the conformity of certain products, before being placed on the EU market, with the applicable essential technical requirements. These essential requirements are publicised in European directives or regulations. A manufacturer can use voluntarily European harmonised standards to demonstrate that a product complies with some (or all) of the EU essential requirements; alternatively, a notified body assess the conformity to these essential requirements. Conformity assessment can include inspection and examination of a product, its design, and the manufacturing environment and processes associated with it. For example, a notified body may designate that a medical device conforms to the essential requirements of the Medical Devices Regulation (MDR (EU) 2017/745) which defines the applicable legislation, including the general safety and performance requirements, for medical de ...

Pressure Equipment Directive
The Pressure Equipment Directive (PED) 2014/68/EU (formerly 97/23/EC) of the EU sets out the standards for the design and fabrication of pressure equipment ("pressure equipment" means steam boilers, pressure vessels, piping, safety valves and other components and assemblies subject to pressure loading) generally over one litre in volume and having a maximum pressure more than 0.5 bar gauge. It also sets the administrative procedures requirements for the "conformity assessment" of pressure equipment, for the free placing on the European market without local legislative barriers. It has been mandatory throughout the EU since 30 May 2002, with 2014 revision fully effective as of 19 July 2016. The standards and regulations regarding pressure vessels and boiler safety are also very close to the US standards defined by the American Society of Mechanical Engineers (ASME). This enables most international inspection agencies to provide both verification and certification services to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
