“…Since the analysis of results from previous two examples in a view of statistical reasoning is small, there are larger researches found through the results of numerous works [26,27,[29][30][31][32][33][34][35]. Also, all these results are compared to results obtained in this work.…”

Study and research on arc welding have provided identification of errors in formulas for calculating the cooling time t 8/5 and other dependent parameters. It is concluded that large errors are present in certain intervals which had caused failures in welding technologies. Incorrect approximation of cooling temperature is replaced by a more accurate approximation used for defining of the new precise algorithm for determining relevant welding parameters.

This paper presents a chronology of how the critical cooling time and preheating temperature in welding have been determined so far. The author of this paper introduces a new approach in calculating preheating temperature using prior art experience as well as his long-term research results in the field of welding. Earlier solutions were based on Rosenthal's 2D and 3D model for calculating the critical cooling time and the corresponding preheating temperature and the improved expressions used by the British Standard. This paper uses the necessary experience in thermal and the corresponding disciplines of mathematics. Problems that occur and prevent efficient obtaining of solvable expressions in a simple and elementary way, the author of this paper solves it in a completely new and inventive way.
