5.6.7 WPQR welding data assistant
The cooling-down time from 800°C to 500°C essential for the welding result (known also as t8/5 time) can
be calculated using the input data in the WPQR welding data assistant. Prerequisite is the prior determi-
nation of the heat input. Upon input of the values, the valid t8/5 time is displayed with a black background.
