Design of experiments (DOE)
had been used in the study, and the results had been evaluated by the
surface response method. The results showed that the welding
current is the main parameter by its effect on the mechanical studied
properties and the parameters values which give the best responses
had been determined.
This research seeks to localize the technology of plasma arc welding (PAW), the best
alternative against tungsten arc welding (TIG). So a quantitative comparison between these
two technologies has been made, according to the particular case that is
DC current.
involving heat efficiency, heat input, tensile strength, relative elongation at fracture, micro
hardness and angular distortion.
