Paper Title
Application Of Quadratic Equations, (Area Of Sector), Properties Of Circle, Trigonometry And Dilution In Production Engineering And Mechanical Engineering

In engineering, welding plays important role. Without use of external heat we get success in welding of Gold and Silver only till today but in future the use of temperature in welding may be reduced considerably. By the application of heat source we are depositing the liquid metal at the joint. The depth up to which the material is liquified is called penetration and there will be raised part of the plane of parent metal called reinforcement. In ideal cases the dilution is considered as 100%. In this paper we are going to use the quadratic equations, area of a sector (properties of circle), trigonometry and dilution in the welding concept (for production engineering and mechanical engineering). Key Words- External heat, considerably, liquified, penetration, reinforcement, dilution.
