The article presents a new methodology enabling the determination of linear welding energy as well as discusses inaccuracy-related issues accompanying the calculation of the aforesaid energy using a commonly applied formula. In addition, the article describes the correlation between the cross-sectional fusion area and energy used to melt the base material and the filler metal. The article also discusses the determination of a coefficient applied successfully in the new methodology and presents its practical application, including the possibility of identifying the heat input also in highly problematic or entirely unquantifiable cases.
