I was surprised the aluminum didn't oxidize/burn/combust when exposed to a naked flame that was hot enough to melt it in the presence of oxygen (air).
Isn't that why they typically use gasses like argon when welding (melting) aluminum, to block the oxygen and prevent it from just burning? I believe they also need to smelt it using a (reductive) electrolytic process for the same reason, instead of just heating it in the presence of carbon like they do with iron ore.
Thank you. Great video. (icymi)
Interesting - BURNING POINTS
GLASS 1,400 - 1,600 F - melting point
Aluminum 1,218 F - melting point
Asphalt 343 F - melting point
Cremation of a body 2,000 F - cremation
Wildfire/Forest fire 1,472 F - Average temperature

argon is used with tig and types of mig.but not stick. and with mig it matters what type of wire your using
