Welding defects
This document provides a classification and overview of common welding defects. It divides defects into three main categories: planar defects, linear volumetric defects, and non-planar defects. Examples of each type of defect are given. The document also describes specific defect types such as cracks, inclusions, lack of fusion, porosity, overlap, undercut and provides potential causes of each.
Metal stiching
This document discusses metal stitching, which is a method of repairing cracks in cast metals without welding. It involves drilling holes perpendicular to cracks and inserting pins that overlap and exert pressure to draw the crack sides together. Two main types of pins - L-series and C-series - are used depending on the application. Metal stitching is used to repair items like propeller hubs, steam turbines, and crankshafts due to its ability to perform repairs onsite with minimal dismantling. The advantages include cold repairs with no distortion, a pressure-tight seal along cracks, and quick return to service.
Metal fracture-mudaking
This document outlines types of metal fracture including ductile, brittle, fatigue, and creep. It defines ductile and brittle fracture and discusses fatigue failure in more detail by mentioning it can occur from repetitive stresses and provide a classic example of fatigue failure. Creep is also listed as a type of metal fracture.
Nut & bolts
Nuts are threaded fasteners that are used with bolts to fasten multiple parts together. Nuts and bolts work together, with their threaded friction and the stretch and compression of parts, to securely hold items in place. Washers are thin, disk-shaped plates that are often used with nuts and bolts to more widely distribute the load. Common materials used for nuts, bolts, and washers include carbon steel, alloy steel, stainless steel, and nickel alloys.
Steel Melting Shop (SMS)
Rourkela Steel Plant was the first in Asia to adopt the LD steelmaking process and the first in India to use external desulphurization. It is also the only plant where 100% of slabs are continuously cast. The steelmaking process in SMS involves charging hot metal, scrap, and fluxes into converters where oxygen is blown to remove impurities through oxidation, producing slag. Molten steel is tapped and further processed before continuous casting into slabs. Waste gases are captured and recycled while dust and slag are also recycled in the process.

Deoxidation and inclusion control
This document discusses the deoxidation of steel and inclusion control during steelmaking. It explains that oxygen dissolves in steel during production under oxidizing conditions and must be removed through deoxidation. Common deoxidizers like aluminum, silicon, and manganese are added as they have a high affinity for oxygen and form stable oxides. The thermodynamics and kinetics of the deoxidation reaction are described. Proper stirring of the melt is important to allow the deoxidation products to float to the surface and be removed. Calcium injection can also be used to modify inclusions and make them more globular and easier to remove from the steel.

Patent Portfolio of Major Indian IT Companies 2010 - Report
The purpose of the study was to analyze the importance given by selected major Indian IT
firms to innovation based on their Patent portfolio as a measure. Analysis of the Patenting
activity provides an insight into current trends in intellectual property generation apart
from providing an account of innovation and technological development taking place in the
Information Technology sector. The study summarizes results of the research that was
conducted on HCL Technologies Limited, Infosys Technologies Limited, Mahindra Satyam ,
Tata Consultancy Services Limited and Wipro Limited.
This report covers filing trends of the above mentioned companies along with status of
Patents, International Patent Classification and Priority Date. The study also provides the
filing trends and status with the field of engineering to which they belong, along with details
of all Patents filed by these companies since their inception.
Our research suggests that after a moderate retrenchment in the years 2008-2009, the IT
industry in India is recommitted to pursue innovation. The fact that the said companies
consider innovation to be one of their key assets and are committed to boost their spending
on Research & Development and innovation is evident from the increase in number of Patents
that have been filed by these companies in US Patent Office, European Patent Office and
Intellectual Property Office India. The study details the challenges associated with software
Patenting in India and postulates that despite the restrictions of obtaining a software Patent
per se in India, the IT industry is taking a prominent stand on generating and protecting
Intellectual Property in India and abroad.
Since the year 2000, awareness about Innovation and Intellectual Property Management
has been on the rise in the IT industry. It is evident from the Patent filing statistics of the
Intellectual Property Office India that the number of Patent filings in the field of computer
science has been on the rise since 2004. Across the world, a large number of organizations
are considering innovation as top priority, and consequently raising the investment on
innovation. In this study, the trends indicate that innovation has been geared towards minor
improvements to existing products and services as against innovation targeting newer
products. However, the companies are broadening types of innovation functions they are
targeting. The emphasis on product development and idea generation is increasing.

Failure analysis of helical gear
This document summarizes the failure analysis of a helical gear used in a steel mill reducer gearbox. Visual examination found two broken teeth with pitting on the contact side. Investigation found the gear material was a low alloy steel and fractography showed brittle fracture from excessive contact stress. The failure was caused by replacing the original motor with a more powerful one, increasing stress over 3 times higher than allowable for the gear material and leading to pitting, crack initiation and growth, and final fracture.
Formability in Sheet Metal Working
This document summarizes formability testing methods for sheet metals. It discusses that formability refers to a sheet metal's ability to undergo plastic deformation without failure during forming operations. Common tests mentioned include forming limit diagrams, cruciform biaxial tension testing, and Ericson and Olsen tests. These tests measure properties like stresses, strains, and ductility. The document concludes that understanding sheet metal formability through these tests provides insight into a material's formability characteristics and deformation behavior.
