Aluminum welding

Hello, I have a couple of problem with aluminum one is a car tire and another an engine of a scooter, which is to be welded aluminum with electrodes, having clear aluminum electrodes, an inverter and welded with the power minine, because it does not come out, I do the material me and do not hit between it, I believe that the failure is that you have to make it a lot of filling, I can endure that

The \ "technical \" is so complicated to detail here that it is as if I explain how my aunt does the donuts that work out so well ...

First of all comment that if the aluminum does not join it is because the surface tension of the material is high, this is solved with the dump, (boric acid for welding with a dodder) and patience first heating the material before welding it.

On the other hand, I tell you that TIG arch aluminum welding has approximately 60% mechanical resistance that welding with autogenous torch, and that lifetime welding (life electrode) special for aluminum, does not even reach 50%. Because small bubbles are formed within the material while welcoming it, somehow as if it were foam.

If you need to weld aluminum, my advice is that you do it with autogenous torch and the same technique that is used for strong welding with brass rod, (very similar to that of the plumbers with tin and copper tubes).

First, they heat the pieces care not to melt them since the aluminum does not change color when it becomes liquid, then the aluminum rod and put it in the borax, and with the flame of the torch giving the pieces, close the rod until it causes the drip of the material on them.

With this technique, the mechanical resistance is 100% with respect to normal aluminum due to the absence of marras bubbles. The issue is that one thing is to explain it to you and another weld.

If they are fine jobs, take them to whom they know how to do them and practice while with other things until sufficient skills.

Greetings and patience !!

I will be shorter, the aluminum welding to autogen

Watch for this topic I have seen a very interesting video that helped me a lot.
In my workshop I do I have to choose to weld with this material I use the tig welder that I have; Together with the "Durafix" rods, which are clean and free of impurities (unlike the aluminum electrode), once the welding is performed, it is stronger than the piece that has been soldier.
