However, when a solid formed or machined projection is used, a solid phase forge weld is produced without melting. The plastic deformation of the heated parts in contact produces a strong bond across the weld interface. Below are some examples of projection designs before & after welding -. Fig 2.
Definition of Inequality. An inequality is a mathematical sentence that uses symbols such as <, â¤,=>, or â¥ to compare two quantities. 5 < d=>< 7,= x= â¥= -= 1,=>2 â¤ b, - 12 > - 13 are few examples of inequalities.
In mathematics, an equation is a statement of an equality containing one or more variables. Solving the equation consists of determining which values of the variables make the equality true. Variables are also called unknowns and the values of the unknowns which satisfy the equality are called solutions of the equation. There are two kinds of equations: identity equations and conditional equations.
