Interpass TemperatureInterpass temperature control involves the monitoring and control of the temperature of a weldment between each welding pass. This may involve providing additional heating to the structure if the minimum interpass temperature is not achieved by the heat of the welding process. Alternatively, it may involve allowing time for natural cooling of the structure between passes, if the heat of welding is such that the specified interpass temperature is exceeded. It is important to know what interpass temperature control involves, what methods of heating can be used, the methods of temperature measurement, and when interpass temperature control should be used.
