| 500 ## - GENERAL NOTE | |
| General note | Welding is a versitile process of metal fabrication that fuses two of more materials for<br/>joining. The choice of welding parameters is a crutial element in planning stage for<br/>producing quality joints. Tungsten Inert Gas (TIG) welding is a high precision welding<br/>technique that uses a non-consumable tungsten electrode in the presence of shielding gas<br/>to produce clean welds. The TIG welding is applicable on variety of metal alloys due to its<br/>controlled parameters ability. The paramount work of this research was to investigate the<br/>TIG welding of distinct stainless-steel grades austenitic stainless steel AISI 304 and Ferritic<br/>Chromium Stainless Steel AISI 430, and analyze the impact of providing distinct nature of<br/>filler materials with controlled welding parameters. The TIG welding is inflenced by<br/>extensive input parameters like welding current, weld speed, arc voltage, shielding gas<br/>flow rate, temperature, and presence of filler material. Preformance impacting factors used<br/>for this study are welding current, filler diameter and shielding Gas flow rate. A<br/>comparative analysis of two different filler materials ER308L and ER410 is produced.<br/>ER308L filler wire produces good mechanical properties when welding disticts metals with<br/>the AISI 304 and AISI 316 due to its strong austenitic weld pool. The utility of ER410 filler<br/>rod in welding AISI 430 material gives strong mechanical leverage over ER308L filler. To<br/>test the mechanical behaviour of AISI 304 and AISI430 welded joint, the experiment is<br/>devided into two sections of ER308L and AISI430 filler based welds. Each set of<br/>experiments were designed using Taguchi L9 DOE orthognal array. The depedency of<br/>mechanical properties, tensile strength, flexural strength and microsctructural hardness was<br/>evaluated using analysis of verience (ANOVA) method. Universal Testing Machine (UTM)<br/>machine was used in conducting tensile and three point bend tests for each sample<br/>produced on fiber laser cutting machine. Rockwell hardness tests (RHT) were conducted<br/>according to ASTM E18 on B00IW5LTBY Gowegroup Rockwell hardness apparatus. The<br/>Optical microscope was utilized for visual analysis of fusion zone, BM and HAZ of each<br/>sample. Tensile tested samples were analyzed under electron microscope for observation<br/>of defect like porosity, penetration of weld, micro cracks, and fusion of metals. |
