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.
The solution set is {x|x â¤ 1}, or (-â, 1]. The graph of the solution set is shown below. Compound Inequalities. When two inequalities are joined by the word and or the word or, a compound inequality is formed. A compound inequality like-3 2x + 5 and 2x + 5 â¤ 7 is called a conjunction, because it uses the word and.
