BAIJIAN - Third party testing organization
Purpose
1. Evaluate whether the welding unit has the ability to weld welded joints that meet the requirements of relevant national or industry standards and technical specifications 2. Verify whether the welding process specification (WPS or pWPS) formulated by the welding unit is correct 3. Provide reliable technical basis for developing formal welding process instructions or welding process cards Meaning
Welding process is an important measure to ensure welding quality、 which can confirm the correctness and rationality of the welding process instructions prepared for various welding joints.
. Through welding process assessment、 the performance of welded joints welded according to the proposed welding process guide book is verified to meet the design requirements、 and reliable basis is provided for the formal development of welding process guide books or welding process cards Scope of application
1. Suitable for the manufacturing、 installation、 and maintenance of steel equipment such as boilers、 pressure vessels、 pressure pipelines、 bridges、 ships、 spacecraft、 nuclear energy、 and load-bearing steel structures.
2. Suitable for welding methods such as gas welding、 electrode arc welding、 tungsten argon arc welding、 metal arc welding、 submerged arc welding、 plasma arc welding、 and electroslag welding
