widely used techniques for joining ferrous and non ferrous metal. The arc is generated between a non-consumable tungsten electrode and work-piece, Argon gas protects the molten metal form any chemical reaction with he surrounding environment. The SS304 material used for experimental work.In this project SS304 sheet material having 3 mm thickness will weld using TIG welding. Keywords: Tig welding, Anova, Taguchi method, Minitab, Stainless Steel.
1. INTRODUCTION Welding, as opposed to lower-temperature metal-joining procedures like brazing and soldering, which do not melt the base metal, is a manufacturing or artistic approach that induces fusion between materials, primarily metals or thermoplastics. A filler material is frequently added to the joint in addition to melting the base metal to create a pool of molten material (the weld pool) that cools to form a joint that can be stronger than the base metal depending on the weld design (butt, full penetration, fillet, etc). (metal parent) To make a weld, pressure can be employed alone or in conjunction with heat. Welding also needs the employment of a shield to protect the filler metals or molten metals from contamination or oxidation. A welding junction is a point or edge that joins two or more metal or plastic parts together. They're created by joining two or more work components (metal or plastic) in a certain shape. Joints are divided into five types by the American Welding Society: butt, corner, edge, lap, and tee. These systems can have a number of arrangements at the joint, where real welding can take place.

3. DESIGN OF EXPERIMENT DOE is a technique of defining and investigating all the possible combinations in an experiment involving multiple factors and to identify the best combination. In this, different factors and their levels are identified. Design of experiments is also useful to combine factors at appropriate levels, each within the respective acceptable range to produce the best results and yet exhibit minimum variation around the optimum results. The design of experiment is used to develop a layout of the different conditions to be studied. An experiment design must satisfy two objectives: first the number of trails must be determined and second the conditions for each trail must be specified. Before designing an experiment, the knowledge of the product/process under investigation is prime importance for identifying the factors likely to influence the outcome. The Design of Experiments (DOE) is a method to identify the important factors in a process, identify and fix the problem in a process, and also identify the possibility of estimation interactions. 3.1Taguchi design This experiment design proposed by Taguchi involves using orthogonal array to organize the parameters affecting the process and the levels at which they should be varied; it allows for the collection of the necessary data to determine which factor most affect product quality with a minimum amount of experimentation, thus saving time and resources.
