MIG with argon

[BigRAWesty]

Pretty interesting, isn't it? Those ugly looking solid wire 'welds' without gas actually welded to the base metal fairly strong. It kinda works as long as I don't move the MIG torch & only hold it in one spot. So, it's kinda possible to do kinda strong weld tacks without gas with solid wire.

Not really. It may look ok from the outside but if you have to cut it open it would look like an aero bar on the inside
