Dear All,
Design code - ASME B31.3
Welding Code - ASME SEC IX
Client Spec Says - Interpass temperature to be monitored and measured during welding.
During PQR I observed that run out length of one electrode was around 75-100 mm.So the welder couldn't complete the joint in a single stretch.In this condition, should I take the interpass temperature before using the second electrode from the first bead end?
More over,the welder can complete the root pass by using three electrodes/filler wire.In this condition should I measure and record three interpass temperatures?ie, first temperature,ambient(starting),second temperature ,during starting of second electrode,Third temperature during staring of third elecrode.
Or one temperature is enough just before starting hot pass?
