Abstract: Argon, helium, hydrogen, nitrogen, oxygen, and carbon dioxide are the shielding gases employed in we ding. Some othem differ greatly in their specific weight, chemical behavior, energy content, and espec ally thermal conductivity, energies of dissociation and ronization, and other properlres. By optimally combining a variety of characteristics, gas mrxtures of particular benefit will be obtained, above all ensuring sound welds and the desired profitability, Examples of a number of materials welded with various pro cesses will be presented and discussed.

Abstract: The medical informatics is a combination of information technology and health care. It deals with the resources, devices, and methods to optimize the acquisition, storage, retrieval and use of information in medical science.It is also known as health informatics.The online medical database system is such a database where all type of health facilities will be stored in online database and this can be access by card. In this paper it proposes the how this card uses for access medical related activities. It is just like ATM card but it deals only health issue. The name of the card is International Medical Card (IMC). It is a application of medical informatics in which all detail of health are stored in the online database and can access by International Medical Card (IMC).
