why would you have to grind and polish the welds ? Does that make it stronger? Will the tourch setup weld 2 pop cans together without burning thru? I ask this cause i am not a welder but am learning and this way I can see if i need to invest in a tourch the one i tried it said to use map gas, it wasn't perty.
Sometimes you have to make a welds look nice cosmetically thats why grinding...No it doesnt make welds stronger .
No,rods won't weld two cans together.Nether can I after 7 years of tig welding. I've heard of stories of folks welding bottoms of aluminum cans together but i never seen one welded.Are you planning on welding aluminum cans together?
The reason i suggested rods is simplicity and affordablility. If you want to spend a few grand just to build a few mufflers -there is a cheap alternatives-aluminum-flux-rods.If you want to make a living doing tig welding then by all means go with highest priced tig rig you can afford.
If you read my previous post i only welded a hole in the bottom of a fishing boat with those rods.It wasn't prettiest weld but it held up and i think today near 3 years later it still there
