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.
In this research, a study of the influence of arc welding
parameters on the thermal cycle was conducted, where the thermal
cycle within the welded plate of stainless steel 304L by plasma arc
welding (PAW) with weld-on-plate was measured using
the
rmocouples for several welding parameters (intensity of the
welding current, welding velocity, flow rate of plasma gas) and
comparing the influence of this parameters on the thermal cycle
within the plate.
