The paper presents the main concepts of a newly-developed numerical code for arc welding simulation and analysis. The new numerical technologies essentially consist first of original methods for the modeling of material deposit allowing a direct simulation of joint formation, instead of usual element birth techniques. Second, a dynamic mesh optimization procedure, allowing error control. And third, a multivariable finite element inverse method for identification of heat sources.
