Welding is basically the art of "gluing" metal with molten metal. One way to generate the required heat is to use an electric arc (arc welding), a very common approach with several variants:

SMAW (shielded metal arc welding/"stick welding")
MIG/MAG (metal inert gas/metal active gas) welding
TIG (tungsten inert gas) welding
...

General Safety

As you might expect from an activity including high electric current, extremely bright light and molten metal, welding comes with many dangers! Do your part so nothing bad will happen.

Personal Protection

When welding, always wear

properly shaded welding helmet
safety glasses for when the helmet is up
welding gloves
welding jacket
cotton clothing (you don't want synthetic fibers to melt on you!)
solid, closed shoes (hot sparks burn through the thin mesh on sneakers)

Suitable Materials

Not all metals can be welded, and some only with certain welding techniques! Your introduction by a tutor will cover the basics, but you may have to do some research yourself in case of more exotic metals.

In any case, do NOT weld galvanized steel! The zinc in the surface coating produces a highly unhealthy gas when burned.

Setup

Due to the smoke and less visible gases involved, we ask you to weld outside in our welding enclosure outside the metal workshop! The curtains will also prevent others from looking into the arc.
