Welding Technology Regulation (18) on Steel Structures in BuildingsJGJ81-2002
The article originates from the national industrial production standard (JGJ81-2002) for the construction of steel structures. It is about the welding technology regulation of the steel structures.
The article consists of 6 clauses. The first clause is about the scope of the regulation. This clause covers the higher technical requirements for arc welding and argon arc welding of steel structures in buildings, as well as for other welding methods like sub-arc welding, electrode shielded heat welding and submerged-arc welding.
The second clause is about the welders and the welding units. It requires that the steel structure welders must be qualified and certified according to their trades. It also requires that welding units must be well-equipped with necessary welding tools, appliances and instruments, and must supervise welding work strictly.
The third clause is about welding materials. The welding materials should meet the requirements of relevant standards.
The fourth clause is about welding parameters. It requires that the correct welding parameters must be used to make sure that the welds are of high quality. The welding parameters should meet the relevant technical requirements.
The fifth clause is about welding procedures. It requires that the welding process should be developed and improved in accordance with the actual situation. The welding procedure should be checked and approved before actually carrying out the actual work.
The sixth clause is about the inspection and acceptance of welds. It requires that the welds should be inspected and accepted carefully according to relevant standards.
The seventh clause is about the repair of welds and welding defects. It requires that all welding defects must be repaired in time, and corrective action must be taken in order to improve the quality of welds.
The eighth clause is about the maintenance of welding equipment. It requires that all welding equipment must be maintained regularly in order to ensure efficiency and safety of operation.
The ninth clause is about the quality assurance. It requires that all welding activities must be carried out in strict accordance with the relevant standards and regulations, and the quality assurance personnel must take the necessary measures to ensure the quality of welding.
The tenth clause is about the documentation. It requires that all welding documents should be kept and filed properly, and all welds should be inspected and tested to ensure that they meet the requirements of relevant standards.
In conclusion, the Welding Technology Regulation (18) on Steel Structures in BuildingsJGJ81-2002 provides a comprehensive set of regulations for welding activities in order to ensure the safety, accuracy and quality of welds in steel structures in buildings. The regulation covers all aspects of welding activities, from the welding procedure to the welding personnel and the welding materials. It is essential for all welders and welding units to adhere to the regulation in order to ensure the welds are of high quality and safe to be used in construction.
