aluminum brazing soldering using alumiweld welding rods

Harbor Freight aluminum brazing or soldering. I don't really know what this process is called. it's called alumiweld so maybe aluminum welding. harbor freight oxy fuel acetylene set

brilliant vid

hi will the rods rust over time after your repairs?

[freddytk421]

@pest2334 It will not rust

It's definately a form of soldering or brazing. It's not welding because the base metal isn't being melted, just the rod. No puddle. It looks it reacts like lead free solder. I've never come across these rods before, I wouldn't have a clue what to do with them either. Exelent video, very informative thanks.

@TheRabidPosum I just called it a welding rod for the search engine.

I like how you show your mistakes and how you show the learning process. This is how I would have to learn and you might have saved me an hour or so.

does this work as well on cast alum?

@rascalwind - also noticed freddy refused to read the instructions that come with the stuff. ie put down the welding rod, pick up the stainless steel scratching rod and scratch the work piece area that is covered by the molten puddle.

You don't do that and the join will never be strong. Got to physically break the aluminum oxide layer by scratching with something other than the alumiweld rod.

And clamp or jig the pieces so they hold still --helps a lot.

Excellent demonstration of how to use Lumiweld as the product is called in the UK

Thanks for posting dude. This has helped me go forward with my little project.

ok, Looks good. You ever welded 0.125" thick material to something as thin as .030"? also i'm using the 1350 grade AL rather than the 6061 as I am trying to do this on a power transformer.

Thanks,

Soldering: below red heat

Brazing: at or around red heat

Welding: melting the base pieces together

Great demo. Keep up the good work
