TIG you’re it!
TIG welding is an arc welding process that uses a non-consumable tungsten electrode to produce the weld.
Last night was the penultimate class of my Creative Metalworking course. It was time for TIG welding and my anxiety was high. I have discovered in the weeks I have been welding that I am very oppossed to wearing the welding mask…so, I’ll let you into a little secret: I asked for help.
Welding brass is very different to welding mild steel where a MIG welder is used: MIG welding or metal inert gas is a welding process in which an electric arc forms between a consumable wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to melt and join.
So with a bit of trial and error and turning the temperature up a little, down a little, we found the balance and tried to weld the first two pieces of the brass cube together.
The weld didn’t hold so I sanded the edges a little to remove some of the grime and also laid a small section of brass wire to bridge a small gap. The welds held after this sanding and my little helper was most efficient at welding the rest of the joins.
With spot welds on the reverse side the cube was completed and the final cube created using copper coated mild steel.
Now to experiment with lighting to create shadow using the connected cubes!
