The best tool for removing aluminum oxide is a stainless-steel brush.

How to tig weld aluminum hole. And for the best results use a stainless wire brush. HOW TO TIG WELD ALUMINUM - HOW TO FIX A HOLE. Keep in mind that it is typically easier to weld thicker pieces at first.

In TIG welding a non-consumable tungsten electrode is used because it has the highest melting temperature among pure metals at 3422 C 6192 F and therefore doesnt contaminate the weld by. First hole was welded with no backing Second hole was welded with aluminum backing third hole was welded with argon backing using a purge box. The trick to not blowing a hole in the can is to begin the arc on the filler wire.

A slightly larger drill bit in a cordless drill is one easy quick way. You can weld on Aluminum cans using a 116 tungsten electrode on your dynasty 200. Tungsten inert gas TIG welding also known as gas tungsten arc welding GTAW is best suited for welding aluminum and stainless steel.

If you pull youll drag the weld at an angle that will create a dirty weld. Make sure you push when you weld and avoid pulling. You should push at a 10-to 15-degree angle only with aluminum.

The same goes for the scotch brite pad not used on anything but the aluminum. Keep the electrode close to the bead for a clean weld. Use a brand-new brush.

The shielding is added through a compressed bottle that provides gas flow to the weld area. Hold the electrode closer to the workpiece. You can use MIG wire as a filler and then start at 20 amps.

An argon purge box is a quick and efficient way to get argon shielding on the back side of stainless for quick repairs like welding holes. Any TIG welder can weld aluminum but there are several factors that will influence the ease quality and appearance of your project. When you get a puddle formed bump your amps to 25 and begin running beads around switching the can between welds.

Next wire brush the weld surface to remove any dirt or contaminants. The welder holds the electrode over the workpiece and melts it by striking up the arc while continuously feeding a filler rod or consumable to the weld pool. For most TIG welding that is 116 of an inchabout the thickness of a dime.

While any TIG welder can weld Aluminum not all TIG welders are created equal. TIG welding is the primary method used to weld aluminum. Clean the aluminum off using a wire brush or a scotch brite pad.

Dont use the stainless steel brush on anything but aluminum. Then weld around the edges of the hole to remove any contaminants without adding filler rod. This process is also known as Gas Tungsten Arc Welding GTAW which is performed by using a non-consumable tungsten electrode with a TIG welder.

In one hand a TIG welder holds a TIG torch that is aimed at the area where one needs to start welding. First you need to clean out the hole with a small stainless steel brush or drill through the hole using a clean drill. The ideal distance from the electrode to the weld puddle is the thickness of the electrode.

Of these the current is by far the most important. Be safe store solvents before you start welding. TIG welding aluminum is a special case.

Ad High Performance Wide Range Structural Adhesives Bonding Plastic and Metal. Aluminum gets covered with a thin almost transparent layer of aluminum oxide that is very tough. The filler metal is a simple wire that the welder feeds and dips by hand which is then melted into the arc.

After you have degreased but before you weld you need to remove this layer. For filling holes in aluminum I usually let the cleaning action of the AC arc clean the area before I actually melt the aluminum. For welding a hole in aluminum sheet metal it helps to clean the hole first.
