Why Use Tig Welding For Aluminium

Gas tungsten arc welding GTAW also known as tungsten inert gas TIG welding is one of the most popular welding processes chosen for aluminum. MIG welding will reduce your work time.

TIG Welding Aluminum Machines.

Why use tig welding for aluminium. Consider MIG welding for aluminium if. To achieve the best welder for aluminum you can try one of the processes. The popularity of aluminum in automotive applications has brought TIG welding to a new golden age.

When you use TIG welding for thinner metals it makes for a much stronger weld. Aluminium is very reactive in nature and at room temperature it forms a layer of oxide on it which makes it impossible to weld through arc welding with straight polarity. It is possible to increase welding speeds in some circumstances by using helium andor heliumargon mixtures.

While any TIG welder can weld Aluminum not all TIG welders are created equal. One of the best choices for welding aluminum is a TIG welder that runs on AC power and you will get many of the most excellent prices. This welding technique is often used by automotive enthusiasts and welders for professional racing teams.

The positive cycle acts as a scrubbing effect on the surface breaking up oxides that limit weld quality this is what you see on the pictures of the perfect welds we see around. Most welders are made for steel so it is important that you make sure you have the right machine for welding aluminumTIG and MIG welders are the best options for the job. Any TIG welder can weld aluminum but there are several factors that will influence the ease quality and appearance of your project.

Especially when we are talking about thin gauge aluminum. For alu welding with a DC TIG you can go electrode tungsten positive but you have to use a thumping big electrode. Ad Quality Welding Machine Tig with Competitive Price.

If your machine sounds like a diesel engine you need to adjust this setting when tig welding aluminum. Pure argon can be used for both GMAW and GTAW welding and is the most popular of the shielding gases used for aluminum. The stronger bond is also why TIG welding is so prevalent in the automotive industry.

Since youre going to weld aluminum using TIG welding youll need to choose either the DC positive or DC negative power. Ad Quality Welding Machine Tig with Competitive Price. The best TIG welding aluminum machines should provide clean starts smooth arc as well as user-friendly settings and relatively more essential features.

This includes argon and a slight composition of helium gas. 1 - Newbies often forget to use the high frequency setting and set it to continuous. To weld it you either need pure Tungsten or Zirconium Tungsten.

But that said not every TIG welder can properly weld aluminum. TIG welding is the primary method used to weld aluminum. This ends up causing the machine to stall at low amperage since the alternating current loses most of its half cycles when the flow of the current is changed.

It is also cheaper. TIG welding is used to weld such reactive materials like Al Mg. The most important thing when TIG welding aluminum to set up is the Tungsten electrode.

Helium has a lower density than argon and higher flow rates are used when welding with helium. TIG welding creates a stronger bond another reason why it is preferred for aluminum and stainless steel. TIG welding is commonly associated with welding aluminum.

TIG Welding Is Stronger. It is easier to set-up and with the welding wire fed automatically the job gets done quicker. The helium content gases are usually more expensive.

When TIG welding aluminium AC or alternating current is used due to the alternating current having positive and negative cycles. MIG welding is better for thicker metal and TIG welding for smaller pieces of metal. An ACDC TIG welder can be used to create high-quality welds with aluminum stainless steel carbon steel copper titanium nickel alloy and more.

Mechanically strong and visually appealing TIG welding is the number one process chosen by professional welders for professional racing teams and the avid auto enthusiast or hobbyist. AC TIG is a great tool to use for welding aluminum because the alternating current essentially cleans the oxidized layer off the aluminum as it welds. The wire in MIG welding is disposable but you want to hang onto the TIG tungsten so the larger tungsten compensates a little for the fact you are frying it with the wrong polarity.

If youve had trouble doing so here are the top 10 mistakes made while Tig welding aluminum. Trusted China Suppliers Verified by SGS. When you might consider MIG welding for aluminium.

Being able to choose between alternating and direct current gives you convenience and flexibility in one machine. Of these the current is by far the most important. TIG welding also uses shielding gas for protecting the overall process from atmospheric contamination.

Trusted China Suppliers Verified by SGS. That Confusing Thing About Aluminum. The polarity of MIG is the reverse of normal TIG.
