 welding procedure qualification shall be carried out by the team participating in the construction of the project. The welders participating in the qualification shall be selected from the welders of the project team and the welders with this level shall have at least one crew member.In fact, another purpose of welding process assessment is to check whether the construction team can master the corresponding welding skills, so as to ensure the overall welding quality of the whole construction team.


 most importantly, the project must have standards for welding quality control and acceptance methods.The welding standards of domestic long-distance pipelines are generally modified in accordance with API 1104 standards of American petroleum institute. The purpose of the improvement is to make the adopted methods and indicators meet the requirements of engineering construction and use conditions.
