 Interpass temperature

Interpass temperature refers to the temperature of a welded joint or the material being welded between successive welding passes. It is a critical factor in welding processes, particularly in multi-pass and heat-sensitive welding applications. Maintaining an appropriate interpass temperature is essential for several reasons: 1. **Material Properties**: The mechanical properties of metals can change with temperature. If the interpass temperature is too low, it can lead to issues such as cracking or incomplete fusion.
