Argon Gas For Mig Welding Aluminum

Disposable Cylinders are generally an 86 Argon 14 Co2 mix which is not ideal for the market that theyre aimed at but its an OK mix. Welding of aluminum is typically done with Argon alone with one exception.

FLOW RATE FOR ALUMINUM MIG WELDING.

Argon gas for mig welding aluminum. Ad Find China Manufacturers Of Aluminum Welding. What process should you use. Pure Argon is still the best gas for any home welder looking to work on some exciting Aluminum projects.

Even a beginner knows that argon is a must for MIG welding a non-ferrous metal like aluminum. It doesnt matter whether you are using the MIG or TIG process. If the aluminum being welded is thicker than ½ of an inch there may be Helium added to the mix.

Disposable Cylinders are generally an 86 Argon 14 Co2 mix which is not ideal for the market that theyre aimed at but its an OK mix. Ad Find China Manufacturers Of Aluminum Welding. A few welds should purge your gas system as would loosening your drive rolls so not to waste wire and pull the trigger for 12-20 seconds at the begining of your weld session.

Pure argon is the preferred shielding gas for welding thin sections of aluminum. Pure argon will give excellent results on all aluminum welding wether it be mig or tig. The typical gas you will need to weld Aluminum is 100 Argon gas.

If needed you could still go with 100 Argon the all around gas for heavy plate aluminum MIG welding. Thicker sections of aluminum pieces may need some mixture of argon and helium for thicker sections where high heat input welds are being deposited. Aluminum MIG Weld done with Argon gas.

Setting your MIG welder up for argon requires you to be fitted with the appropriate contact tip ventilation equipment and gauges. Pure argon is the most popular shielding gas and is often used for both gas metal arc and gas tungsten arc welding of aluminum. An argonHelium mix the most common being 25 helium is ideal for tig or mig welding aluminum over 14- 50 he for over 12 and 75 he for over 1 inch.

A Argon Helium The mixture of Argon and Helium is normally applied for MIG Welding Aluminum nickel and stainless steel. Argon is the main shielding gas used for Tig Welding most metals and Mig Welding Aluminium or Mig Brazing. If you normally MIG weld mild steel using C25 gas dont worry you can use the same gas hose and your regulator designed for Argon gas.

Or Argon O2. Argon gas by itself works well on most exotic metals like. Aluminum has an interesting property that requires a specific gas to be used while welding.

Shield Gases like oxygen have much higher pressure and can lead to a huge safety threat due to it with pressures near 3000 psi Gases Shield Gas. Argon is the main shielding gas used for Tig Welding most metals and Mig Welding Aluminium or Mig Brazing. This process is a very smooth transfer of molten metal droplets from the end of the electrode to the molten pool.

MIG Welding Gas for Aluminum Welding. Because aluminum is a non-ferrous metal it requires a 100 percent argon shielding gas. Welding thicker pieces of Aluminum 14 inch to 12 inch then you may well find a mix of Argon and Helium better for deeper penetration.

Aluminum is non-ferrous metal and therefore you should only use 100 argon as the shielding gas. Flow rates of 20 to 30 cubic feet per hour are recommended. Argon Gas for Aluminum Welding MIG Welding Aluminum Filler Electrode Wire Selection.

For a pure 100 percent argon shield gas a flow rate of 20 to 30 cubic feet per hour is recommended when welding aluminum. Your weld power contactor and gas solenoid do operate at the same time. Argon is most commonly used in combination with oxygen and carbon dioxide although pure argon is used for non-ferrous metals.

Mixtures of argon and helium are probably the next common and pure helium is generally only used for some specialized GTAW applications. Excellent welds are often produced using pure argon as a shielding gas. Choose the right gas.

Stainless Steel MIG weld done with C2 gas. Argon is one of the most commonly used shielding gases in MIG welding. There are basically two gases that are suitable for aluminum welding.

Simultaneously the idea of a gasless procedure has a fair share of appeal to the industry. When MIG welding aluminum the desired mode is spray transfer. The helium mixed into the Argon helps create a hotter arc to penetrate aluminum.

The ArgonHelium mixture is only used on aluminum that is thicker then 12 of an inch. GAS FLOW RATE FOR MIG WELDING. As I said earlier argon requires a higher flow rate and the recommended flow rate to be used on aluminum is 20 to 30CFH.

Two-part MIG Shielding Gas Mixtures also known as Binary Mixtures are often the combination of either. This gas is perfect for both when it comes to dealing with Aluminum and other non ferrous materials. You really shouldnt have gas problems at the start after your gas system is purged.
