The focus is to study and explore the Welding input parameters for Gas Tungsten Arc Welding (GTAW) of elevated temperature piping used in Power Plants and to predict the Weld�s Hardness on construction sites. The study is based on Design of Experiment (DoE) taking the important parameters into account and analyzing each of them. The data generated through experiments has been validated for the hardness based on input process parameters (welding current, welding voltage, travel speed, welding rod diameter) and the findings from the study revealed that the most important factor influencing the hardness of a Creep-Strength Enhanced Ferritic (CSEF) material welds is the Voltage while other factors have minimum or the least influence for the studied ranges and factors. © (2014) Trans Tech Publications, Switzerland. date: 2014 publisher: Trans Tech Publications Ltd official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84913535229&doi=10.4028%2fwww.scientific.net%2fAMR.1025-1026.310&partnerID=40&md5=ce21759ffa513b401678859b7d4d4f0a id_number: 10.4028/www.scientific.net/AMR.1025-1026.310 full_text_status: none publication: Advanced Materials Research volume: 1025-1 pagerange: 310-316 refereed: TRUE isbn: 9783038352549 issn: 10226680 citation: Sarwar, M. and Abd Majid, M.A.B.
