The welding coordinator of the plant or the fabricator shall select from Table 6 the test piece as required for the production work on which the welder is to be employed. Two complementary specific test pieces (TP5 and TP6) may also be chosen as defined in 4.4 and 4.7.1.
The welding operator qualification tests are classified according to welding process and welding machine type.
NOTE Machine type within the scope of this document stands for longitudinal, orbital, circumferential and robotic welding machines.
For multiple welding machine types, additional qualification shall be at the discretion of the responsible welding coordinator.
The welding operator has to show theoretical knowledge of the welding process.In the practical part of the qualification test, the welding operator shall demonstrate competency in operating the welding machine according to an established WPS.
A test weld of any type of weld with a process on a given welding machine type shall qualify for all product types/semi-finished products and all types of welds with this process and this machine type.
The test weld can be performed on dedicated test pieces or production parts.
Depending on welding positions in actual production, the welding position of the test piece shall be chosen in accordance with Table 2, Table 3, Table 4 and/or Table 5.
A test piece welded in the fixed position also qualifies for welding parts when not in the fixed position,e.g. rotational turntable for tubes.
TP6 shall be welded in PA or PB, which qualifies for all welding positions for in-process welding of castings in casting facilities.
NOTE 1 Tube welding has overlapping start and stop points. This is not the case for sheet or plate welding.
Therefore, test pieces with tube (TP3, TP4 and TP5) do not qualify for sheet/ plate.
The range of qualification for each welding position is given in Table 2, Table 3, Table 4 and Table 5.
The welding positions are specified in ISO 6947. The test pieces shall be welded in accordance with the nominal angles of the welding positions in accordance with ISO 6947.BS ISO 24394 pdf free download.
