3.Preheat (if required)- Minimum temperature is being maintained in accordance with WPS.

4.Interpass temperature-
   Maximum temperature is in accordance with WPS.

5.Welding consumables-
   In accordance with WPS and being controlled as procedure.

6.Welding parameters-
   Current, volts, travel speed are in accordance with WPS.

7.Root run-
   Visually acceptable to Code before filling the joint (for single sided welds).

8.Gouging/grinding-
