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.
Here is an example: Consider the inequality. When we substitute 8 for x, the inequality becomes 8-2 > 5. Thus, x=8 is a solution of the inequality. On the other hand, substituting -2 for x yields the false statement (-2)-2 > 5. Thus x = -2 is NOT a solution of the inequality. Inequalities usually have many solutions.
