Monday Blues with Lab Session

I personally hate Monday. It's the beginning of the new week, where usually new weeks brings in new expectations, new targets and of course the weekly routine of wearing formal clothes. Blardy rules...

But not this time, I've a way to fend off these weekly routines. With a little trick and some creativity added into your daily lives, you can accomplish something which is extraordinary into your routines.

After the long ramblings above, all I did was simple : skip class la... takyah pakai baju formal~ takyah sibuk banyak banyak dgn hair-styling... bazir wax aje.

But, in the afternoon there's a Manufacturing Lab session. After messing up the DE and moral classes together, this class however, must not be missed. It carries a very heavy load in Lab Sessions and none in Finals exams because there's no finals exam for this subject in the first place. And the lab session for today is...

Learn to pump oil??
Well, think again! It's gas welding for today! 3 main things for this cool baby to do is to pre-heat a surface for shaping, joining 2 metal surfaces and even cut the metal. Yeah, dont' look down on this baby, a misaim from the user will certainly cause alot of barbers to go bankrupt since it's easy to make others bald with that torch.

Ahh... a spark!!
The gas welding has two main gas, acetylene and oxygen. Acetylene is used because it's easy to combust as similiar to ammonia, though it cannot rival with ammonia in terms of stinkyness. Oxygen is the assisting combustion agent. According to the lab instructor, the item above (as seen in picture) is used to create a spark. Just point the tip of the nozzle there with acetylene turned open and u will get a small flame. Too much acetylene instead will create a big flame, which is dangerous. Then the oxygen tap is turned open so the flame changes colour from yellow to blue (as similiar to Bunsen Burner). Take note that with different amount of oxygen that's mixed with acetylene, a different form of flame is produced, and each of these forms has different temperature. With the coolest is 3100C and the hottest is at 3300C.

This is no child's play.

Today, our task is simple. Just draw 2 lines across the metal slabs given by the instructor. Though we were somewhat unhappy cause we can do alot of stuff with this tool apart from 'drawing 2 lines'. Nevertheless, we agreed not to spend the whole 5 hours in the lab. So we get down to business as quickly as we can.
A lapse in concentration can lead to disastrous ending...
this is what I see through the cyclope's goggles (safety goggles)
After 'drawing' the lines and dip it into a bucket of water to cool it, this is the final product of the metal...

On the left is the metal before going through hell. On the right is the one that got burnt, scarred, dunked and dried. Pretty neat huh?

Overall, this lab experiment has given me a great experience as to handle the welding tools. Despite all the fun, there's one more thing left to do...

HAND IN THE LAB REPORT WITHIN ONE WEEK!!

So much for the fun. Sigh...
