Porosity is a cavity-like discontinuity and occurs due to the entrapment of gases in the molten weld pool. These entrapped gases don't get a chance to escape from the molten weld pool and hence cause porosity.

<h3>Which discontinuities are caused during welding?</h3>

Weld discontinuities can be defined as "an interruption of the typical structure of a weld, such as a lack of homogeneity in the mechanical, metallurgical or physical characteristics of the weld." Porosity is considered to be the most critical discontinuity. Weld discontinuities include porosity, incomplete fusion, excessive melt.

The first five positions to be named as Grand Prize winners are not give any order.

Therefore, the number of ways they can be selected is

_{5}^{22}\textrm{C}

_{5}^{17}\textrm{P}

\frac{17!}{12!}

17 x 16 x 15 x 14 x 13 ways of ordering

Therefore, the number of ways in which the entries can be announced is

\frac{22!}{17!5!}\times 17\times 16\times 15\times 14\times 13

= 19554575040 number of ways

Thus the announcement can be made in 19554575040 number of ways.
