How To Tig Weld Aluminum With Dc. 4043 works best and produces a clean bead. The argon cools the tig torch, shields the tungsten, and stabilizes the arc. However, tig weld aluminum can have a direct current (also referred to as “dc”). Tig welding also uses shielding gas for protecting the overall process from atmospheric contamination.
Welding Basics & HowTo TIG Weld Livestream Part 1 of 2 From pinterest.com
When tig welding thick aluminum (¼ inch), dc polarity is recommended as it provides deep penetration and strong weld with a single pass. Place the base of your gloved hand on your table for support. Dc is not ideal for welding aluminum, and instead, an ac current should be used. Dc (direct current) tig welding is acceptable for aluminum workpieces as well. The shielding is added through a compressed bottle that provides gas flow to the weld area. An aluminum fertilizer spreader, or an aluminum bracket on a conveyor, or an aluminum pump housing , all might be examples of things that can be repaired if someone just has a dc tig welder.
Since you’re going to weld aluminum using tig welding, you’ll need to choose either the dc positive or dc negative power.
This is because aluminum has basically two layers, the base aluminum, and aluminum oxide. Remember, aluminum oxide (or alumina is a ceramic, and is very brittle, so it breaks off easily. However, tig weld aluminum can have a direct current (also referred to as “dc”). You can weld aluminum to most other metals relatively easily via adhesive bonding or mechanical fastening. To avoid this, you must isolate the other metal from the molten aluminum during the arc welding process. With all of that in mind, you can still get quality welds on aluminum with a tig machine running direct current.

In order to weld aluminum one needs to remove the oxide layer. Tig welding aluminum with a dc current: Initiate the arc and perform the cleaning action; Use helium gas if you choose to use the dc tig welding method. The best electrodes for tig welds with direct current are 2% lanthanum tungsten rods.

This includes argon and a slight composition of helium gas. In order to weld aluminum one needs to remove the oxide layer. However, this technique is recommended more for thicker workpieces due to the greater depth of penetration. He’s put together a great video that walks you through the details.

Using his “ideal” situations for tig welding aluminum on dc as a starting point gives us a good starting point for putting together a plan. Form the weld puddle and add filler rod You can also use 5356 rods, but the welds tend to be rough and won’t look good. The rule of thumb for tig aluminum is to use 1 ampere for every thousandth of material thickness. Ultimate smaw guide, have a look at it.

Tig” at weld.com recommends the dc setting for specific situations. Meaning, welding a base material that is 12.5mm or 1/8 thick would need 125 amps. Use helium gas if you choose to use the dc tig welding method. Initiate the arc and perform the cleaning action; Ac polarity is not recommended while tig welding thick aluminum plates as it won’t provide you a deep penetration and strong weld with a single pass.
