Hello Kary

KARILUZ QUARANTA dice:

hello mafe, how are you?

Mafe García dice:

Fine... Today tell me about Iron & Steel.

KARILUZ QUARANTA dice:

well, this is an interesting topic because it is related with our careers.

do you know about advantages of iron and steel over stone and brick?

Mafe García dice:

Yes, I know some things about that... Iron can be model to any form in contrast to stone or brick, these materials have physical features that can't be changed

KARILUZ QUARANTA dice:

Yes, that is an interesting feature. Also, Unlike the bricks and stones with steel and iron could produce stronger structures that are manufactured with less material

Mafe García dice:

I agree, make a structure with iron and steel is cheaper than stone or brick

Kary... What is the importance of steel and iron after the 20th. Century?

KARILUZ QUARANTA dice:

well, I did not know to much about that topic but I think that with Iron and stell humanity could do structures more resistant at the same time, are materials very cheaps.

Mafe García dice:

Oh... great..

KARILUZ QUARANTA dice:

Iron is soft in its natural but cast iron can resist compression, fire and corrosion. All these advantages led to the use of cast iron in architectural designs.

Mafe García dice:

Amazing... . Steel is one of the strongest materials used as structural support in the important constructions because is strong in tension and compression

KARILUZ QUARANTA dice:

yes, that is great

but tell me do you know about characteristics of steel?

and what do yoy say about disadvantages of steel and what solutions have been found?

Mafe García dice:

Well, steel is Heavy and thus expensive to transport.. Also is susceptible to corrosion- steel structures must be painted continuously

This material has a high expansion rate in changing temperatures and In conditions of repeated stress and changing temperatures, can suffer fatigue and cracks... And the most important energy intensive to produce.

tell me about what is welding?

KARILUZ QUARANTA dice:

well, nothing is perfect in this world jajjaja

Mafe García dice:

Jajaja, THAT'S TRUE!!!

KARILUZ QUARANTA dice:

well, welding is a very important process on engineering, also, I could tell you that Welding is a process fabrication that consisting to joins materials. You can use different kind of energy sources like flame, an electric arc, a laser, an electron beam, friction, etc.
