In today's dynamic changing environment, for industries to remain internationally competitive, traditional manufacturing techniques used for welding have to become more flexible and intelligent to attain better adaptability and higher productivity. In industrial applications of MIG/MAG welding processes, various types of shielding gases are used based on type of work material and weld quality required. In this proposed research, experimental studies will be conducted on welding productivity by using different shielding gas combinations. The aim of this project is to conduct experimental analysis on weld arc phenomenon, weld pool behavior, and weld quality and to build an intelligent system for the selection of optimum combination shielding gas mixtures. In addition this study also aims to examine how the microstructure and mechanical properties of different welds are influenced by the use of different shielding gases combinations.Read moreRead less

The proposed work seeks to develop an improved tool for more accurate design data and improved materials selection criteria for critical equipment and infrastructure maintenance in major Australian industries, where environmentally-assisted cracking is a serious concern (viz., marine, polymer/chemical processing, aeronautical, alumina mineral processing and pulp-and-paper). A successful validation of the novel testing approach (namely, Spiral Notch Torsion Test (SNTT)) for evaluating the stress corrosion cracking (SCC) susceptibility of materials of practical interest that are difficult or impossible to adequately characterize by conventional tests, is as much a fundamental research challenge as its accomplishment will be industrially attractive.Read moreRead less

Stress corrosion cracking (SCC) represents a serious threat to infrastructure exposed to chloride and caustic environments. The proposed project will characterize the chloride-SCC crack propagation parameters for a super duplex stainless steel, which is the material of construction for vessels for stripping vinyl chloride monomer in a PVC processing plant. Alarmingly high numbers the welds (nearly 50%) in the vessel had suffered extensive pitting (which is a well-known SCC initiator) and SCC cracking. For the mitigation measures, the project will also investigate pitting and SCC susceptibility of weldments of alternative varieties of stainless steels, such as Zeron 100.Read moreRead less
