The imagination palace 14

    

We looked at each other

We said in amazing matter,"

What do you mean with that?

There is no tie between ours

At all you said,"

You will weld the iron

How could you do in fine?"

My son got puzzled

I continued,''

You may know

When you want to connect

Between two cloth

You sewed them

When you want

To connect wood

You use bolt

When you want

To connect iron

What will you use?"

He looked in disturbance

I said,'' using welding

We heated two surfaces

Of the same iron metal

Look the same iron metal

We first clean the surfaces

By using abrasive tool

Then we made them tended

In angles to be filled

With the tied metal

It must be the same metal

It must surrounded by isolated powder

To prevent air enter

As the air is danger

For welding matter

We made the two surfaces in near

Making some difference

We heat them

And heated the tying

Till they melted

We put the melted in

 It filled the gap

And the tending gate"

My son asked,"

Is it the same angle?"

I said, "No,

For moderate pressure

We use low angle

In moderate action

Or low pressure action

We use high angle

In high and great action

And in high pressure action

Now the types of welding

First if you use gas in heat

It called gas metal arc welding

The second is

Tungsten inner welding

The heating is being by inner gas

The third is

Arc welding

The heating by electricity

The fourth is

Gas or oxy acetylene welding

We can use machine

To get our aim

In ease in speed

The conditions are

Clean surfaces

Tending surfaces

Heating process

The welding is completing"

My son asked,''

Are those types?''

My neighbors said,"

No, types of welding

As the welding surrounded

In close or open weather

Above or under water

In salty or sweet water

It different according to weld

The process in plates or pipes

In plates it used in tanks

Or cars or bridges

Or others

It may be in horizon,

And vertical action"

My son sad,"

So welding may be complicated

And danger at health

I have easy thing

I use gum

After chewing

And clean surfaces well

And put it between them,"

We looked at ours

We said,"

Gum!'
