Aluminum is very predominant metals with different alloying elements like: magnesia, silicon, tin, copper, magnesium and zinc. Important discussion for the field of metallurgy and engineering due to having fabrication & formability for the different products. In the world of precision TIG welding provides the best and suitable processes used in nuclear industries, automobile industries, aerospace industries and marine industries. In this book, we used the details of TIG welding on the different samples 2mm, 3mm and 5 mm thickness on 5052 aluminum alloy plate.Welding speed, gas flow rate & welding current are the final governing parameters in this book. Also, the output parameters after several readings on the taken sets of specimen are studied and various optimized step by using RSM (Response Surface Methodology), And MINI TAB Software taken for the better quality of welded joints and their strength of weld. Tensile strength and hardness of weld joint will analyze over the specimen through the optical microscope and UTM.

The purpose of research in this book is to cut a 1mm thick Carbon fibre reinforced polymer (CFRP) by using a low power CO2 laser cutting speed (1-2mm/sec) and assist gas pressure (1-2bar). Main objective of this research work is to lower production cost of cutting by using lower laser power. A Composite of Carbon Fibre (carbon fibre + epoxy resin) with initial dimensions of 120mm 100mm 1mm was used as a material for laser cutting. A CO2 laser machine of maximum laser power 150 watt was used for laser cutting. Rectangle cuts of 50mm 40mm were cut through CFRP sheets. Samples size was determined according to response surface methodology (RSM). Factorial design was used to determine number of experiments. According to this design, number of experiment was eight. Experiments were conducted according to this design. Experiments were conducted by changing process parameters (laser power, cutting speed and assist gas pressure) simultaneously. After laser cutting, scanning electron microscope was used to see effect of process parameters on material surface in the form of microstructure. Optimization was done by the use of MINITAB software.The purpose of research in this book is to cut a 1mm thick Carbon fibre reinforced polymer (CFRP) by using a low power CO2 laser cutting speed (1-2mm/sec) and assist gas pressure (1-2bar).
