Sažetak
Hardfacing or hard surfacing may be defined as the application of a hard, wear resistant alloy to the surface of a softer metal to restore it dimensionally and reduce wear caused by abrasion, impact, erosion and heat. The benefits also include the minimization if downtime needed to replace worn part, reduce spare parts inventory and saves money. This study investigates welding parameters for semi- automated hard surfacing process of AISI 316 stainless steel substrate with open arc iron- based tubular wire filled with fused tungsten carbide. The goal was to find near optimal welding voltage, torch speed, wire feed rate, gas flow rate and torch angle of robotics welding machine for deposition process. Because, welding wire filed with tungsten carbide is expensive, our goal was to find near optimal welding parameters for deposition of predefined thickness height above substrate. In order to achieve the above objective, a set of mathematical models has been developed for the prediction of height of deposited material. Genetic Algorithm computational model was used for the optimization of welding parameters to achieve desired thickness of deposited material.
