Description 397-404
The present work investigates the micro plasma arc welding (MPAW) of SS304L of 0.5 mm steel sheets. It primarily
highlights the weld quality of SS304 of 0.5 mm thickness with and without post weld heat treatment (PWHT). Thin sheets
are more prone to distortion at time of solidification because of residual stress induced. After PWHT of the welded sample,
the distortion is reduced. The effect of input parameters such as pulse current, gas flow rate and welding speed are taken into
consideration. Property evaluation and comparison of weld are carried out before and after the PWHT by hardness, tensile
test, microstructure, X-Ray Diffraction (XRD) and scanning electron microscope (SEM). Furthermore, artificial neural
network (ANN) is applied for optimization of the weld quality at chosen process parameters and compared to that of the
experimental results by considering tensile strength as an output. The ANN will be useful for estimating the welding current
to yield an optimum tensile strength, thus providing better process control.
