1 Scope
This standard specifies requirements for qualification test of welding operators for automatic welding and fully mechanized welding. Only welding operators responsible for performing the programming of the welding unit and/or adjusting parameters during welding have to be subjected to qualification test.
This standard is applicable to qualification test of welding operators for fusion welding (automatic welding and mechanized welding) and resistance welding of steel, aluminum and aluminum alloy.

GB/T 3375 Welding terminology
3 Terms and definitions
For the purposes of this standard, the relevant terms in GB/T 3375 and the following terms and definitions apply.
3.1 function test
test of a welding unit set-up in accordance with a Welding Procedure Specification (WPS)
3.2 pre-production welding test
welding test having the same function as a welding procedure test, but based on a non-standard test piece, simulating production conditions
3.3 production test
welding test carried out in the production environment, the main characteristic of such a test being that normal production is reproduced during this test
3.4 production sample testing
sample testing of actual welding products sampled from a continuous production using the welding unit, no interruption of normal production during sampling being necessary
3.5 programming
incorporation of the welding procedure specification and/or the specified movements of the welding unit into a programme
