WELDING OF CAST IRON Cast iron is an extremely versatile material‚ used in thousands of industrial products. It is hard‚ wearresistant‚ and relatively inexpensive. Like steel‚ it is available in many different grades and compositions. While we usually think of cast iron as being brittle (having low ductility)‚ this is not true of all cast irons‚ as we shall see shortly. Cast iron‚ like steel‚ is an iron-carbon alloy. In composition and structure‚ and in some of its properties‚ it is quite different

Lang‚ Member‚ IEEE‚ and Pradnya Nagarkar Abstract-This paper presents a detailed discussion of micromotor fabrication and related critical issues. The micromotors under study are of the variable-capacitance side-drive type with salient-pole and wobble (harmonic) designs. Polysilicon surface micromachining forms the basis of the micromotor fabrication process. In this process‚ LPCVD heavily

At this moment the company is working hard to rebuild a good image in the market after some customers dissatisfaction with late job deliveries. To resolve it is important to increase the communication and cooperation between the engineer department and manufacturing. Other issue is to keep and increase the welding capabilities in the company. The company
