After we all learnt te weld metal with TIG, we moved on to welding with aluminum. welding with aluminum is a lot harder than it sounds and looks.
You must be very carful that aluminum doesn´t melt beacuse his melting point is lower than other metals.
First we tried to just add the material to the aluminum plate, and even that was hard. Then we tried to weld 2 plates together, and aluminum welds very different from other materials beacuse you have to drag it slowly. But even if u drag it slowly the weld wouldn´t stick to the other plate. It gave me a hard time and alot of nerves were lost.
My best aluminum weld looked like this.
After that we started to make a dice from aluminum but we ran out of time. I learnt alot about welding in this 2 weeks.
