The type of electrode that you select (unless it is stipulated on the drawing or by an authority) will be based on too many factors to list here. But here are a few.
To match the material to be welded.
To meet certain specs Ie. tensile strength, maleability, abrasion resistance,
protect the base metal from acids-corrosion-salt water-chemicals etc.etc.
To match the type of electrical current produced by the welding machine.
The position you will be welding. Flat,Vert,O-head,Horiz.
The amount of weld you want to lay down with each pass.
The thickness of the base metal.
The cost of the electrode.
Cleanliness of the material. Dirt, Paint, Zinc etc.

What is the meaning consumable welding?
Consumable electrode welding contain the processes where the electrode acts as the filler material and the electrode that generates the arc. Because the electrode is also the filler material, the electrode 'burns' or is consumed, hence consumable electrode.
What does the E stand for on a welding rod?
It stands for electrode. As opposed to R ( rod) for gas welding or TIG welding. If it carries electrical current it is an electrode.
What does en indicate on a welding rod?
The letters EN , on a welding electrode , indicate "electrode negative" , that is the electrode is to be used with a DC current , in the negative position, or polarity.
What type of welding is E6022 electrode used on?
for welding dingeberries
Electrode that is used up during welding is said to be?
If you are referring to the small unusable piece of welding rod that is left after welding, most call it a electrode stub.
What are the functions and characteristic of welding electrodes?
what is normal welding electrode and how it welds
When welding the flux on an electrode?
shielded metal are welding is also called
What is the electrode required for welding mild steel pipe with EN 19 forging?
what is the recomended welding electrode for EN-19 greade
What type of welding which do not require a molten electrode?
TIG welding electrodes do not melt under most applications. Electrode means it carries electrical current. In MIG welding the wire becomes the electrode. In TIG and Gas Welding the filler material is called a rod. Stick welding uses rods called electrodes.
What is up hand welding?
Uphand welding is welding with the electrode pointing upwards, above the hand.
What is the meaning of SMAW Welding?
Shielded Metal Arc Welding, commonly called Stick welding. A shielded electrode passes a current between itself and the workpiece. Both the base-metal and the electrode are melted by the current and the electrode is consumed and deposited into the melted puddle forming the weldment.
