This paper analyzes the domestic and international standards or specifications for friction welding operator qualification certification
including ISO standards
AWS specifications
GB standards
and aerospace and aviation standards. It also compares their differences in scope of application
examination details
and recognition range. The study finds that ISO standards have strong versatility and a wide range of applications
but for specific welding methods
it is necessary to refer to the corresponding special standards; AWS specifications are formulated according to industry characteristics and are more suitable for welding production under the American standard system; GB standards transform ISO standards and have a relatively narrow scope of application; aerospace and aviation industry standards have established strict welding operator qualification certification requirements for the aerospace field. It is recommended that enterprises choose appropriate standards or specifications for qualification certification based on their own certification system
industry characteristics
and welding methods
and pay attention to the scope of application
examination details
and recognition range of standards or specifications to ensure that welding operators obtain the required qualification certificates and reduce corporate costs.
