A Welding Procedure Specification (WPS) is a formal document describing welding procedures. It is an internal document used by welding companies to instruct welders (or welding operators) on how to achieve quality production welds that meet all relevant code requirements. Each company typically develops their own WPS for each material alloy and ...
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 ...
Weld quality assurance. 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. [original research?] In manufacturing, welds are used to join two or more metal surfaces. Because these connections may encounter loads ...
Dye penetrant inspection (DP), also called liquid penetrate inspection (LPI) or penetrant testing (PT), is a widely applied and low-cost inspection method used to check surface-breaking defects in all non-porous materials (metals, plastics, or ceramics). The penetrant may be applied to all non-ferrous materials and ferrous materials, although ...
X-ray vault used in Radiography. Nondestructive testing (NDT) is any of a wide group of analysis techniques used in science and technology industry to evaluate the properties of a material, component or system without causing damage. [1] The terms nondestructive examination (NDE), nondestructive inspection (NDI), and nondestructive evaluation ...
Weld tests for friction welding. Quality requirements of welded joints depend on the form of application, e.g. in the space or fly industry weld errors are not allowed. [1] Science try to gets good quality welds. There are many scientific articles describing the weld test, e.g. hardness, [2] [3] [4] tensile tests. [3]
Computed Tomography (CT), a subset of radiographic testing, is proving useful for the inspection of thermoplastic composite welds. CT involves the computerized building of a 3-D image using X-rays taken from numerous, incremental angles. It is particularly useful for the determination of fiber orientation in welds of glass reinforced composites.
The basic welding symbol which goes on the reference line to indicate the shape of the weld such as a fillet or plug. The symbol is placed on the arrow side or other side of the line to indicate which side of the joint the weld goes. The dimensions and other numbers such as the length of the weld or number of spot welds go above and below the ...
