Definition of the Mathematical Model Coefficients on the Weld Size of Butt Joint Without Edge Preparation

[摘要] This paper represents the definition methods for thermal constants according to the data of the weld width under the normal-circular heat source. The method is based on isoline contouring of "effective power - temperature conductivity coefficient". The definition of coefficients provides setting requirements to the precision of welding parameters support with the enough accuracy for an engineering practice.
