Abstract: TheTIG welding or gas tungsten arc welding (GTAW) process is widely used in many appliances because of its versatility in industry. For GTAW process, metals like carbon steel, stainless steel, aluminium, copper, low-alloy steel and non-metal also are widely used in all positions. Butt joint, lap joint, T-joint, edge joint and corner joint are the common types of joints used in welding. The incompletely fused spots like porosity,which occurs after welding is known as lack of fusion that leads to undesirable results; and to overcome this, it requires change in welding techniques and parameters within the limits. A large number of resources are used nowadays for reworking the welds. But it causes higher cost of production and delay for completing the work. Higher amount of rejection of product may generate if the lack of fusion is not to be controlled physically during welding. This work is aimed to predict and reduce lack of fusion with TIG welding process parameters. Using various design of experiment methods, straight and indirect effects of the process parameters can be determined and process parameters can be optimized. 2019-01-01T00:00:00Z http://10.9.150.37:8080/dspace//handle/atmiyauni/2251 Title: Parametric Optimization of End Milling Operation on EN24 Steel Shaft of Grinding Machine Authors: Acharya, Ghanshyam 2022-01-01T00:00:00Z http://10.9.150.37:8080/dspace//handle/atmiyauni/2247 Title: Development of maze puzzle algorithm for the job shop scheduling Authors: Kagthara, M.S.; Bhatt, M.G. Abstract: Maze puzzle concept has been introduced for solving job shop scheduling problem. Maze puzzle algorithm (MPA) is based on rotation and random jumping which explores the solution space as well as exploits the solution near to optimum. Coding is done using MATLAB software, and benchmark problem is evaluated for assessing efficiency of the algorithm. The algorithm can be used for optimisation of makespan for the given problem. The results are compared with other methods like GA, SA, SBI, SBII, PSO, BBO and TS, and found better than GA, SA, SBI, PSO, BBO but poor than SB-2 and TS. 2022-01-01T00:00:00Z http://10.9.150.37:8080/dspace//handle/atmiyauni/2244 Title: Optimization of Process Parameters Influencing Lack of Fusion Defect in TIG Welding of SS 304 Thin Sheet Authors: Shah, Sagarkumar Abstract: Tungsten Inert Gas (TIG) welding or Gas Tungsten Arc Welding (GTAW) process is widely used in many appliances due to its versatility in industry.
