A more detailed and accurate study of the thermal phenomena involved in arc welding processes is of great importance for both simulation developers of metallurgical transformations and residual stresses generation and users in general, whom need to understand this phenomenology to take decisions. In terms of thermal phenomena, heat input and its derivatives (such as thermal efficiency and fusion efficiency are the most representative parameters in welding engineering. However, scientific and technical literatures are very divergent on heat input values. In addition, they do not discuss the actual heat flow inside the plate. Initial tests demonstrated that these inconsistencies are due to systematic and random errors that occur duri...
