This only melts at approximately 2015 degrees Celsius, but aluminum itself, depending on the alloy, melts at around 650 degrees. This means that the aluminum would run away while the oxide layer was being melted, making welding impossible.

Websome welders like the way aluminum welds with a nicely rounded tip. There is something to be said for welding aluminum like this, but the problem is at low amperage on an edge, the arc wanders pretty bad. Thats why I use a blunt taper, the arc is better at low amperage and then the tip balls naturally as needed as amperage increases. WebMay 13, 2024 · Practice steadying the arc by holding the electrode about 1/8 to 3/16 of an inch from the work piece, then begin moving along the path you want to weld. As you move the electrode, the metal will be melting away, filling the pool of molten metal and building your weld. [11] 13.
