Alcance y aplicabilidad

This standard applies to the safe implementation, operation, management, and supervision of welding and cutting operations. It covers various processes including oxy-fuel, arc, resistance, electron beam, laser, brazing, and friction welding. It is mandatory for all personnel and facilities involved in these operations within China.

Requisitos técnicos

The standard outlines general safety requirements including the establishment of a controllable safety management system, defining responsibilities for managers, supervisors, and operators. It mandates proper equipment maintenance, personnel protection, and the use of warning signs in hazardous areas. It specifies detailed requirements for work area protection and personal protective equipment (PPE), including eye, face, and body protection against radiation, sparks, and noise. The standard also addresses ventilation requirements to control hazardous fumes, especially when dealing with low-limit materials like lead or cadmium, and outlines strict fire prevention measures. Specific safety protocols are established for confined spaces, requiring special ventilation, atmospheric testing, and the presence of attendants. The standard also introduces new safety requirements for public exhibitions and detailed operational guidelines for various welding methods such as laser welding, electron beam welding, brazing, and friction welding. Managers must ensure all operators are certified and properly trained.

Métodos de ensayo

The standard primarily focuses on safety protocols and operational procedures rather than specific product testing methods. However, it references various inspection and verification procedures, such as atmospheric testing for toxic and combustible gases in confined spaces, equipment leakage checks, and radiation inspections for electron beam welding systems. Compliance with these inspection procedures is mandatory before commencing work.
