3.5.1 Basic Requirements
3.5.1.1 All welders participating in the welding work for this project must hold a valid special equipment operation certificate issued by the Market Supervision Administration, with certification covering the material types and job requirements specific to this project; such certification may not be obtained through a combination of multiple individuals holding certificates for different items.
3.5.1.2 All personnel engaged in work at height (2 meters or more) must hold a valid high‑altitude work permit issued by the Emergency Management Bureau. Any work involving hot work must be performed by individuals holding a welding and thermal cutting certificate.
3.5.1.3 Welders shall be between 18 and 55 years of age, in good health, and free from any occupational contraindications.
3.5.1.4 No welding quality incidents or records of nonconforming welds in the past two years (must be confirmed by a written commitment from the bidder, stamped with the official seal).
3.5.2 On-site Practical Assessment
Prior to commencement of work and following the signing of the contract, all welders proposed by the contractor must pass a site‑based practical examination organized by the Employer (using material grades P11 or 15CrMoG, with pipe diameter and wall thickness no smaller than the project’s maximum specifications). Only after their weld joints have been certified as compliant through radiographic and surface inspections may they be assigned to duty. Personnel who have not undergone assessment, or who fail such assessment, are strictly prohibited from entering the worksite. For welded steel structures, the required certification level may be lowered; however, all welders must still undergo an entry‑level examination.
