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.
The American Welding Society held this location for 30 years before buying its current property in Doral, Florida – only seven miles northwest of the old facility. [citation needed] In August 2012 the American Welding Society moved from their longtime headquarters just outside Coral Gables to their current location in Doral. During the grand ...

According to the American Welding Society (AWS), a WPS provides in detail the required welding variables for specific application to assure repeatability by properly trained welders. The AWS defines welding PQR as a record of welding variables used to produce an acceptable test weldment and the results of tests conducted on the weldment to ...
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.

The Robotics Certification Standards Alliance (RCSA) is a global company that has been actively providing robotics curricula, training, online testing systems and certification since 1998. RCSA first started with partnerships with Motoman and Private Career Colleges in Canada. The partnerships grew to have included ABB, Motoman and Panasonic.
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] The weld structure can be examined by optical microscopy [3] [4] [5] and scanning electron microscopy.
