Weld monitoring methods ensure the weld's quality and correctness during welding. The term is generally applied to automated monitoring for weld-quality purposes and secondarily for process-control purposes such as vision-based robot guidance. [citation needed] Visual weld monitoring is also performed during the welding process. [citation needed]
Bend test coupons for welding procedure qualification. 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.
During welding, defects or flaws can develop. In some cases, these flaws could potentially affect the integrity of the weld, [1] resulting in failure by fatigue, creep, brittle fracture, or yielding. [3] Therefore, codes to determine weld quality must be developed. Traditionally, welding codes have been based on workmanship criteria.

Gas tungsten arc welding, because it affords greater control over the weld area than other welding processes, can produce high-quality welds when performed by skilled operators. Maximum weld quality is assured by maintaining cleanliness—all equipment and materials used must be free from oil, moisture, dirt and other impurities, as these cause ...
The metalworking industry has instituted codes and specifications to guide welders, weld inspectors, engineers, managers, and property owners in proper welding technique, design of welds, how to judge the quality of welding procedure specification, how to judge the skill of the person performing the weld, and how to ensure the quality of a ...
