Readers are invited to explore the fascinating world of Tungsten Inert Gas (TIG) welding and its profound impact on P22 (2.25Cr-1Mo) and P91 (9Cr-1Mo) steels. Through meticulous research and experimentation, the author unveils the complexities of these dissimilar weld joints commonly used in power plants.
The book delves into the behavior analysis of P22 and P91 steels after TIG welding, particularly focusing on the challenge posed by the high hardness values in the heat affected zone (HAZ).
Readers will find a wealth of information on microstructure and mechanical properties of the weldments, as well as metallurgical examinations before and after welding and PWHT. The research encompasses statistical techniques like one-way ANOVA, providing a robust analysis of the behavior of parent materials following TIG welding. The findings are reinforced by vivid metallurgical images, aiding readers in comprehending the intricate details of weld pool formation and HAZ transformation.
This book is an indispensable resource for welders, researchers, and industry professionals seeking to optimize TIG welding practices and enhance their understanding of the behavior of P22 and P91 steels. With its focus on sustainable PWHT processes, it equips readers with the knowledge and techniques necessary to mitigate hardness disparities and ensure the durability and reliability of weldments.
A case study has been conducted to prove the efficacy of Six Sigma approach, as far as poor Cpk index is in question. This work represents a successful case study which will ultimately motivate the practitioners & quality engineers to inculcate Six Sigma in their respective job-floors, for reaping the associated financial and non financial benefits. This study will be further helpful for researchers, academicians and industrialists (especially in developing co
A case study has been conducted to prove the efficacy of Six Sigma approach, as far as poor Cpk index is in question. This work represents a successful case study which will ultimately motivate the practitioners & quality engineers to inculcate Six Sigma in their respective job-floors, for reaping the associated financial and non financial benefits. This study will be further helpful for researchers, academicians and industrialists (especially in developing countries) to bring overall process excellence among various sectors of supply chain beside their existing constraints in today’s cut throat market environments.

In this study, effect of carbide precipitation analyzed on the metallurgical and tensile properties of gas tungsten arc welded austenic stainless steels. The yield strength, ultimate tensile strength, percentage elongation and metallographic studies are done to evaluate the effect of carbide precipitation. The multi-pass GTAW process is used for the fabrication single V and double V welded butt joint of the stainless steel plates. The tensile shows done on the
In this study, effect of carbide precipitation analyzed on the metallurgical and tensile properties of gas tungsten arc welded austenic stainless steels. The yield strength, ultimate tensile strength, percentage elongation and metallographic studies are done to evaluate the effect of carbide precipitation. The multi-pass GTAW process is used for the fabrication single V and double V welded butt joint of the stainless steel plates. The tensile shows done on the single V and double V welded joints carbide precipitation does not affect the yield strength and UTS significantly but ductility suffer worse from 12 to 20 % due to the heavy carbide precipitation . The tensile studies also reveal that the Double V weld joint showed better tensile properties as compared to the single V welded butt joints. The micro-structural studies showed that weld metal showed dendritic structure and as the post weld thermal aging was induced the extent of carbide precipitation increases. The micro-hardness studies concluded that BM showed the highest micro-hardness and HAZ showed the least, as the post welded micro-hardness values showed decreasing trend due to the carbide precipitation revealed in the micro-structure.
The book contains vauable information as far as Impact behaviour of 316L steel welds are concerned. Its useful for stell industry practitioners and academicians. The steel having more than 11.5 % chromium added to iron those steels are known as stainless steel. In this fine layer of chromium oxide formed spontaneously on the surface of steel which is exposed to air, this layer act as a barrier to further rusting, oxidation or corrosion. In stainless steel 316,
The book contains vauable information as far as Impact behaviour of 316L steel welds are concerned. Its useful for stell industry practitioners and academicians. The steel having more than 11.5 % chromium added to iron those steels are known as stainless steel. In this fine layer of chromium oxide formed spontaneously on the surface of steel which is exposed to air, this layer act as a barrier to further rusting, oxidation or corrosion. In stainless steel 316, the molybdenum which is present in it plays a major role in weldability. Grade 316 L is the advanced grade of 316 grades where L stands for low carbon. This advanced grade is immune of sensitization which is generally known as grain boundary carbide precipitation. This grade 316L provides good toughness, surface finish at both room and cold work temperature. This Book is about the influence of sensitization on the impact behavior and on microstructure of AISI stainless steel 316L
