Suppose Source A is required to reduce a unit of total phosphorus (TP) from the river. For whatever reason, it costs Source A $100 to clean up that unit. Source B, on the other hand, can clean up a unit for $80. Under WQT, there is room for Source A to pay Source B something less than $100 but more than $80 for Source B to clean up that unit of TP.

WELDER PERFORMANCE QUALIFICATIONS TEST (WPQT) While WPS and PQR are used to define and prove the welding process. WQT/WPQT is used to test the actual welder. Is the welder able to produce a sound weld, with the following. • With a particular welding process ie. GMAW or GTAW. • In a given position Horizontal, Vertical or Overhead.
