CE 2.1 Project InformationName of the project:Effect of Welding heat on Weldment Corrosion of Austenitic andFerritic stainless steelLocation of the project: Sydney, AustraliaProject Duration:(Please fill)Organization: UTS BroadwayRole and Designation during the time: Mechanical EngineerCE 2.2 Project BackgroundCE 2.2.1 Characteristics of the projectI had carried out this project work on “effect of the welding heat on weldment corrosionof austenitic and ferritic stainless steel”. Corrosion on weldments of the stainless steel is turnedinto a constraint for wide application. The factors those are affecting weld pool, as well as itsquality, are fabrication methods, weldment design, humidity contamination, a contribution offoreign particles, absorbent with the formation of a cavity, expansion of residual stress inaddition to former metallurgical factors. I had focused on welding methods and techniques forconducting the project work. I had evaluated various welding conditions with the dissimilaramount of heat applied in addition to cooling rate plus analysed the corrosion manners of theweldment. I had analyzed various scientific article and literature review and established thatformation of heat affected zone (HAZ) throughout welding reasons modification on anintergranular structure. It results in the formation of various granular arrangement on HAZ

evaluated to a natural arrangement which results in weak joint understanding along withvulnerable corrosion joint. CE 2.2.2 Objectives developed for the projectFollowing are the objectives of this project work:To analyze effect of welding heat on weldment corrosion of austenitic and ferriticstainless steelTo study the cause of corrosion on weldment of stainless steelTo analyze solid waste welding technique for ferritic stainless steel and austeniticstainless steelCE 2.2.3 My Area of workI had used of metal alloys such as Nickel, molybdenum and others for enhancing ofcorrosion resistance and non-metals used to improve its mechanical property. I had mainlyfocused on this project on a consequence of chromium content on the corrosion resistance. I hadanalyzed consequence of welding heat on stainless steel based on corrosion resistance. Due tosupper mechanical properties of austenitic and ferritic stainless, they are used in the industry. Myproject work suggested that lessening of carbon and nitrogen help to improve corrosionresistance.
