Purpose: of this paper is to determine the possibility of of thermovision method application in the thermal cycle of Inconel 625 on 13CrMo4-5 steel pad welding thermal cycle analysis. Design/methodology/approach: Single- and multibead pad welding of steel 13CrMo4-5 by superalloy Inconel 625 has been carried out by means of GMA method in inert gas backing shielding, in horizontal position and 620 J/mm and 2100 J/mm heat input level. Quantitative data concerning infrared radiation emission as a basis for evaluation of thermal history of the applied object in order to assist interpretation changes occurring in padding welds and heat-affected have been obtained on the grounds of infrared radiation measurement by means of Flir Systems ThermaCAM SC2000 PAL infrared camera. Findings: As a result of the performed inspection, temperature distribution in the weld made by heat input energy E = 2100 J/mm; of cooling, both cooling curves of padding welds and HAZ during single- and multi sequence pad welding have been determined and also single bead self-cooling time and durability time during single bead pad welding. Practical implications: The full suitability of thermovision analysis of thermal cycle of pad welding. Specified self-cooling times will become a base for inference about microstructural transforms in HAZ, whereas cooling rate settlement determines necessary conditions to maintaining required intersequence temperature for assumed heat level input of pad welding, padding weld temperature in self-cooling time function and particular. Originality/value: The thermovision effect and thermal cycle of Inconel 625 on 13CrMo4 -5 steel pad welding thermal cycle analysis has been no yet determined.
