Typically you will use a Pure Tungsten, identified by the green band at one end of the electrode. It is less susceptible to contamination and provided good cleaning action due to the orbital shape of the ball and the conical shape it gives to the plasma stream providing a stable working arc.
Using 2% thoriated tungsten works well if you are limited to tungsten resources. 2% thoriated tungsten is marked with a dark red band around one end of the electrode.

What welding process uses a non consumable electrode?
consumable is when the rod or other metal is also used up in the weld, like common mig welding. Non consumable would be like forms of tig welding that don't use any rods or other metals to join the 2 materials together. This is the Distance
What element is used as the metal in domestic light bulbs?
tungsten <<>> Also along with the above, aluminium for the shell, steel for the filament holders, and in past years brass was used for the shell until manufactures found out it was cheaper to use aluminium for the job.
What materials use for bulb?
A Light bulb uses glass for the casing, brass/aluminium for the screw or bayonet mount, tungsten for the filament, copper alloy for connecting wires and porcelain for insulation.
What welding processes use constant current arc welding machines?
Constant current arc welding machines are primarily used in processes such as Shielded Metal Arc Welding (SMAW), Gas Tungsten Arc Welding (GTAW or TIG), and some variations of Gas Metal Arc Welding (GMAW). These machines maintain a consistent current level to ensure stable arcs, which is especially important for manual and precise welding applications. SMAW and GTAW benefit from this characteristic, as they allow for better control over the weld pool and electrode.
What are the methods of tack weld?
Tack welding methods include several techniques, such as spot welding, where small welds are made at specific points to hold materials in place temporarily. Another method is the use of stitch welding, which involves creating a series of overlapping welds along a joint. Additionally, gas tungsten arc welding (GTAW) or gas metal arc welding (GMAW) can be employed for tack welding, providing precise control and versatility. Each method ensures stability and alignment before final welding processes are completed.
What is the fusion welding process?
Fusion welding is a process that joins materials, typically metals or thermoplastics, by melting the workpieces at their interface, allowing them to fuse together upon cooling. This method often involves the use of an external heat source, such as an electric arc, gas flame, or laser, to achieve the necessary temperature for melting. The molten material solidifies as it cools, creating a strong bond. Common fusion welding techniques include arc welding, gas tungsten arc welding (GTAW), and gas metal arc welding (GMAW).
What are the uses of tungsten composite?
You can use ordinary tungsten to mark
can i use grant for welding school?
can i use grant for welding school
welding i want to weld steel bars to my trailer should i use a arch welder or a wire feed welder?
arch welding is a more stable form of welding. it get hotter and creates a stronger bond
What is cs welding?
CS Welding is known as Carbon Steel welding that is more beneficial and easy to use for welding purpose.
Use of center lathe for Friction welding?
Centre lathe can use for friction welding.
