Abstract : This paper presents the development of mathematical models for austenitic stainless steel (316 L) cladding deposited by gas metal arc welding (GMAW).The weld quality depends on the welding process parameters like welding voltage, welding current, welding speed, bead offset, etc. The heat input to the cladding process influences bead geometry, composition, ferrite content, microstructure and corrosion properties. The bead geometry influences the number of welding passes required to deposit the given surface area. The percentage of offset influences the dilution of filler metal and thickness of the deposited layer. Dilution reduces the alloy content of the deposited later and degrades corrosion resistance properties. The simulation results shows that the parameters wire feed rate and welding speed has significant impact on the bead width and height of reinforcement.
