Why Engineer me? well because lately, I that's what I have been doing. At work, been reading lots about engineering and its quite interesting, but hard. Its practical stuff that the average dooude has no clue about.

Things like welding. Look I had no idea about how complicated welding can be, but apparently in steel, you can add other materials in order to make that steel stronger (which is good for buildings and stuff) but when it comes to welding, it causes heat affected zones (HAZ) and the welded part decreases in strength by 30% (in comparison to welding non treated/strengthened steel) which could lead to micro fractures (which is bad). To my understanding, you then need to neutralise the HAZ by instead of putting, say, a 900c heated steel onto a normal temp base steel, you should heat up that base steel to about 600c, and therefore slow down the cooling process, therefore more effective welding.

LOL If I am wrong. correct me.

There is other stuff that I am learning about things like Process Plant, tailings dump, scrubber, cyclones, puddle... so many new terms! What has stumped me is "tracer test" but this entry is already getting hell boring. I bet you all have stopped reading by now. *sigh*
