Best Tungsten For Sheet Metal

Tig stands for tungsten inert welding and in a more technical sense it s known as gas tungsten arc welding gtaw.

Best tungsten for sheet metal.

They are best for welds with titanium alloys copper alloys nickel alloys and non corrosive steel. A 5356 filler metal. Typical aluminum alloys for sheet fabrication are 3003 and 5052. The gold 1 5 lanthanated tungsten electrodes contain slightly less lanthanum than their blue counterparts and are best used in dc applications.

Compared to the balled pure tungsten used with conventional tig welders a pointed electrode provides greater arc control and enables you to direct the arc precisely at the joint to minimize distortion. Because it will have you a lot more control over the whole process and it is more forgiving in case you do anything wrong. This might be obvious to you but for tig welding really thin metal its best to taper the electrode like a needle. The best two electrodes for welding auto body sheet metal is either ceriated tungsten or thoriated tungsten.

Ditch a 1 8 inch tungsten electrode for something much smaller like 1 16 inch tungsten. Tungsten heavy alloy sheet contains tungsten content ranging from 80 98 with small amounts of molybdenum nickel iron and copper elements. With good heat resistance tungsten is usually used in high temperature applications.

There are various tungsten electrodes that you can use for the process but not all will. Pure tungsten is a hard lustrous and silvery white metal. After going through the mixing pressing and sintering process tungsten is combined with the other metal elements beginning as a form of powders. Tig welding thin sheet metal with a 3 32 2 4mm tungsten electrode.

Filler metals for either of these would be 4043 or 4943. You also definitely dont want any grinding marks running sideways. The process utilizes a non consumable tungsten electrode that relays current to the welding arc. For welding at high amps those sideways scratches dont make that much difference.

These electrodes perform best in dc welding at low current settings but can be used proficiently in ac processes. 90 8 06 oz 17 89 17 89.
