To weld aluminum operators must take care to clean the base material and remove any aluminum oxide and hydrocarbon contamination from oils or cutting solvents.
How to weld aluminium sheet.
For mig welding sheet metal it is often recommended to use an electrode wire of the smallest diameter to prevent burn through and warping.
Aluminum oxide on the surface of the material melts at 3 700 f while the base material aluminum underneath will melt at 1 200 f.

Also it will ensure that you don t get any warping of the materials you are working on and no burn through as well.
It makes for a very strong bond and with a little practice can be done quickly with great looking results.

Forget the larger 1 8 inch tungsten electrode and use a smaller one.
How to weld aluminium to steel.
The main reason to use a smaller diameter wire is that it takes less heat for melting and hence the metal around the weld is not heated to a very great extent.
Knowing how to weld aluminum is a matter of assembling the right tools exercising caution and patience and gaining experience.
Aluminum is a relatively soft thin lightweight metal while steel is much tougher heavier and thicker so joining the two can be very difficult.

The welder lays a bead of molten metal that becomes a slag free weld.
The arc is struck with the electrode wire protruding about 1 2 in.
There are two easy methods for welding aluminum to steel although both require more time and work than ordinary welding.
Welding any material is a challenging process but welding lightweight metals like aluminum requires the utmost precision to ensure a strong bond.
The electrode wire must be clean.

Turns out you can weld aluminum without a welder.
To weld sheet metal with solid wires use electrode positive ep or reverse polarity.
Don t attempt to weld thin materials like sheet metal with flux cored wires which put more heat into the base metal.
