How to Use Aluminum Cans to Prevent Creosote Hunker
As the cans burn in a very hot fire the manganese in the aluminum is released which causes the crusty tarry creosote to break down and flake and turn into powder. While the creosote powder or flakes may end up in the firebox and be easy to clean out the next day it could also be caught in the elbows of the stove pipe if you have a wood stove.

WeldingWikipedia
Welding is a fabrication process that joins materials usually metals or thermoplastics by using high heat to melt the parts together and allowing them to cool causing fusion.Welding is distinct from lower temperature metal-joining techniques such as brazing and soldering which do not melt the base metal.. In addition to melting the base metal a filler material is typically added to the
