welding engineer makes a WPS for the welder to follow as it is a small test of the WPQR.

the welder makes the test sample with the WPS. a welding inspector records all of the welding conditions made to make the sample. an independent examining body may be requested to monitor the procedure.

the sample is subjected to NDT in accordance to the methods specified, Eg visual inspection, dye penetrant, magnetic particle.

then the sample is destructively tested Eg tensile, bend, macro etch. the client may require additional tests such as hardness and toughness.

the WPQR is made from the welding engineer. it gives details of.:

welding run conditions

resuilts of NDT

results of destructive tests

welding conditions allowed for production welding.

welding engineer makes a WPS for the welder to follow.

the welder then makes a test weld following the WPS. the welding inspector monitors them to ensure they are following the WPS.

the test sample is subjected to NDT in accordance with the methods specified by the standards. some destructive tests may be required.

the welders qualification is prepared showing the welding conditions used to test the sample.
