Table 9
Heat Input (kJ/mm) = Volts x Amps x 0.06
Travel Speed (mm/minute) Steel Plate
The following information applies to repairs on steel plate used for the structural components of the machines. This information does not apply to engine, transmission, hydraulic components, or non-ferrous components.Cooling Rate
Limitations on both preheat and heat input are necessary to ensure that the heat affected zone cools at an appropriate rate.Cooling is controlled by a balance between preheat and heat input for a particular plate thickness and joint configuration.Preheat, Interpass and Heat Input
The following preheat, Interpass and heat input tables will ensure that the cooling rate of the heat affected area is satisfactory.

MS106 75 °C (170 °F) 300 °C (570 °F)
MS107 125 °C (260 °F) 300 °C (570 °F) Do not exceed the maximum interpass temperature. The interpass temperature is measured 50 to 75 mm (1.97 to 2.95 inch) each side of the weld, one minute after the weld pass has been made.Excessive interpass temperatures can adversely affect the mechanical properties of the parent metal behind the heat affected zone.Note: Do not overheat the plate. Extra distortion can be induced by too much preheat.
