Interpass temperature
WebNov 11, 2015 · Staying above the minimum interpass temperature keeps the area around the weld from cooling down too quickly. When welding martensitic stainless steel, it is imperative that you hit an accurate preheat temperature and maintain the minimum interpass temperature the entire time you’re welding. Otherwise, you’re likely to end up … WebThe preheating temperature is the lowest temperature before the first welding pass which has not to be fallen below in order to avoid cold-cracking. For multi-layer welds this term refers to the temperature of the second and the subsequent weld passes and is also called interpass temperature. In general the two temperatures are identical.
