A practical based determination of preheating temperature of high strength steels welding
Abstract
This study introduces a straightforward method for calculating preheating temperature in steel welding, combining hardness testing with graphical representations of cooling time. The approach begins with hardness tests on welded joints, providing essential insights into material behavior under different cooling conditions. Graphical diagrams are then created to illustrate the relationship between hardness values and cooling times. These diagrams facilitate the selection of optimal cooling times for desired hardness levels. By integrating these diagrams with an existing C++ program, preheating temperature can be easily determined based on the chosen cooling time. This streamlined approach enhances the accuracy of preheating temperature calculations, ultimately improving weld quality and structural integrity.
