Experimental and analytical evaluation of preheating temperature during multipass repair welding

ABSTRACT
Experimental measurement and analytical calculation of preheating, i.e. interpass temperature during multipass repair welding has been presented. Analytical calculation is based on heat transfer analysis, whereas measurements have been performed by thermovision camera. Repair welding was performed on crane wheels in the Steelworks Smederevo. Comparison of results indicated that analytical calculation is good enough as the first approximation, but it needs further elaboration, e.g. taking into account the radiation component of heat dissipation and/or temperature dependence of material thermomechanical properties.
