In calculating heat input (amps x volts x 60/IPM) on a weld, I'm interested in getting opinions on how much impact preheat and interpass temps have vs. the heat input itself as calculated by the traditional formula shown. None of the technical papers I've found incorporate anything but the four factors in the above formula, so my thought is that while preheat and interpass certainly have a role and cannot be completely discounted, their respective dominance in calculating heat is minimal (i.e., 80% calculated heat input and 20% preheat and IP temps). Any thoughts?
