Some weldors only use Oxy/Acet to weld with. I've used it on steel, aluminum, brasses and bronze as well as silver soldering and brazing. If I had only one process available to use Oxy/Acet would be my choice as you can cut, braze, heat and weld with it. It is the process of choice for artists and craftspeople.
Be very careful with that set oxyacetylene tanks. I'm getting ready to do some oxyacetylene welding.
mixture of oxygen and acetylene (oxyacetylene)
grade ten
the left hand thread is for acetylene use only
The best fix would be to weld it yes. To do a proper weld on aluminum you are going to want to only use a TIG welder. You can also have decent results with industrial J-B Weld. The area would need to be properly prepped and cleaned though for best results.
I would use epoxy, J B Weld or Araldite.
en 24 grade which welding rod use?

Yes, you can weld steel to steel. You can use steel welding rod.
When welding something like gears, you need a rod that gives good penetration, and also has a fairly high density. I would probably use 6011 rods. These are the best for any "out of position" weld. Just be sure it's a close weld. Otherwise you'll get a lot of spatter (which you would then need to grind off).
weld up planet gears more you weld the better just to stop them from turning,dont recommend for road use though!!!
Argon gas is an inert gas and it shields the weld from any contamination from the out side air. It shields the weld and makes it cleaner and stronger.
