Need help using alumalloy. Never used it before.
I got some of those alumalloy rods to try to join a couple pieces of aluminum. Not having much luck. First tried a propane torch, then tried a map gas torch, then tried putting pieces of concrete on top of what I was trying to join to retain the heat better. The Alumalloy rod is bending from the torch but won't melt along the joint I need it to.[image

Incase anyone is wondering, yes that is an upside down Barbie scooter I'm trying to recycle into something else. Maybe it's acting too much like a heatsink?

Is that an anodized finish you trying to work on??

You might want to try putting the part on a hot plate and heating the entire thing up. Thick sections can be difficult

You need to constantly brush with the SS wire brush. The exposed aluminum pieces oxidize immediately so while you have the molten puddle of rod material you scrub through it to get the bond while it’s shielded from the atmosphere. Once the rod has some purchase it sticks to itself pretty well and you can get some build up.

Let the heat from the part melt the metal, not the flame from the torch. Sort of like lead soldering.

Are you saying you can't melt the welding rod with the torch you have?
Also, have you ever seen a butane lighter explode? It's pretty dramatic. You might want to get that away from the work area.
