With the application of ISO 3834-2 standard, the continuity of manufacturing under controlled conditions at establishments that are involved in manufacturing by welding is ensured.

• ISO 3834 standard, has been prepared to determine the appropriate terms of quality for manufacturers using welding in their manufacturing, by taking welding by melting of metals as the base method.
• ISO 3834 standard is only related to the quality of the product that may be effected from welding or welding related procedures and its main rules involve providing guidance for determining the required requirements of quality for manufacturing that involves welding and is carried at the establishment or site, and the welding capability of the manufacturer concerned. The Standard is used as the basis for assessing the welding quality systems of manufacturers.
• The controls for manufacturing that involves welding starts in the design stage and continues as follows;
  - Selection of materials
  - Selection of filler material
  - Training of welding coordination personnel
  - Certification of the welders employed
  - Determination of welding methods
  - Conducting of manufacturing that involves welding
  - Controlling the quality of manufacturing by using test methods that involve destructive and non-destructive testing.
