How To Tig Aluminium Welding

Generally avoid using very lightweight light-duty TIG torches on aluminium you risk burning the torch out. When TIG welding aluminium torch set-up is critical.

Welding aluminum requires superb performance at low amperage and sometimes getting a welder with amp specifications that go.

How to tig aluminium welding. 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. Once the material has a thickness of over ¼ inch the rule of the thumb starts to deviate and not as much amp is needed. As you start welding be sure to allow the weld puddle to pool before you introduce the filler rod.

A tig welder basically comes with both ac and dc power options. Because due to the high welding integrity and good appearance of the process it provides how-to Tig weld aluminum. The shielding is added through a compressed bottle that provides gas flow to the weld area.

If playback doesnt begin shortly try restarting your device. With TIG welding youll need to learn how to control the gas. Skipping this step often results in wasting good aluminum.

Tips for MIG welding. The rule of thumb for TIG aluminum is to use 1 Ampere for every thousandth of material thickness. How to TIG Weld Aluminum part 1.

Meaning welding a base material that is 125mm or 18 thick would need 125 amps. Electron beam welding has a very precise heat affected zone that can be easily controlled. If the base material is 14 inches thick the rule deviates a bit so we dont need that much amperage.

Keep the torch in a steady forward-moving position with a slight backward tilt of 5 to 15 degrees. However aluminum welding presents other challenges from modeling the heat into dealing with the oxide layer. 0125 requires about 125 amps.

If you have too much argon going into your torch youll wind up with an off-centered arc. How to TIG Weld Aluminum on DC. 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.

It requires three things heat a shielding gas and filler metal. Make sure the torch has a suitable duty cycle for the amperage youre using. You should also consider using a heat sink when performing your TIG weld.

Generally speaking TIG welding is the process of fusing metal with metal. Prepare your push-pull wire feed Clean your aluminum remove any oxide and file the edges that will be joined Avoid pulling while weldinginstead push at a 10 to 15 degree angle. Gas Tungsten Arc Welding GTAW has been regarded as the leading aluminum welding method.

We basically use a rule of thumb when it comes to TIG welding aluminum which demands that 1 amp should be used for thousandth 0001 of material thickness welded. When looking for a TIG welder for welding aluminum you have to be extra keen on its amperage range as well as amperage control. Hold the torch by bracing it with the base of your hand from your wrist to the tip or your pinky finger flat against the table.

The aluminum can hold the heat for quite a while and tig machines are. The heat is created by the electricity passing through the tungsten rod. Part 1 TIG Time - YouTube.

A heat sink will keep the aluminum from warping. Therefore welding a base metal of 18 in. You can do aluminum do it using ac and dc both.
