Which can give you the best experience on tig welding.
Easiest way to weld aluminum.
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.
Tungsten inert gas tig welding is the primary method used to weld aluminum.
You can heat the workpiece by putting it directly in an oven or you can use a propane torch to apply heat to the surface.
The first requires an inverter supply of power.
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.
Many tools and methods are designed for welding steel but aluminum requires its own technique and equipment.
Aluminum is much easier to weld when the work is already much hotter than room temperature.
The latter requires a constant voltage and current machines.
Because the aluminum work piece requires a lot of heat to get up to temperature but can hold that heat for a long time a welding machine with current control is useful for keeping the aluminum work piece from overheating causing a burnthrough.
When you are trying to select the best welder you should decide whether you ll use pulse welding or spray arc welding methods.
With the square wave inverter technology it becomes a prominent welder for aluminum.
You can weld stainless steel as well as thinner gauge materials.
The three best ways in which to attempt to weld aluminum safely are to clean the surface of the aluminum use a heat sink process when welding and preheating the aluminum.
The best way to weld aluminum welding aluminum comes down to choosing the right welding process.
Aluminum should be thoroughly cleaned prior to welding including the removal of any lubricants from the material.
To mig weld aluminum thinner than 14 gauge 074 inch it may be necessary to use specialized pulsed mig or ac tig welding equipment.
Well it s not only for welding aluminum.
Each of these methods should work to make the weld of your aluminum easier and safer.
