It melts. Avoid moisture. To cover the weld. ------ Plus adds alloying ingredients, determines the type of electrical current to be used (AC - DC or either), slows the cooling rate of the puddle to temper the weld, tells you what position you can weld in (flat,horiz,vert,overhead), protects the molten puddle from harmful gasses in the air by creating smoke and slag, determines how much amperage you will need to use, shapes and contours the weld bead and much more.
To get a good seam, you need to protect the melted metal from the oxygen in the air. The coating of the electrodes melts on use and provides that protection. The melted coating also helps in removing oxidization and surface impurities from the metal to be welded.
how do you calculate welding electrode consumption
No not all electodes have a flux, in some cases such as certain M.I.G welding the electrode resemble bare wire because it has no flux?
shielded metal are welding is also called
350degree
E - Stands for Electrode 60 - 60,000 tensile strength. 1 - in all position welding can be done 0 - cellulose
There is a coating on electrode. It absorb moisture from an atmosphere. To remove moisture from it, we have to back that electrode up to 300 ' C. If we dont heat this electrode, there is a chance to get discontinuity in welding. Ketan Baraiya
The designation E6011 means: E=electrode 60=60,00p.s.i.tensile strength as deposited 1= all position 1=coating make up
how do you calculate welding electrode consumption
Five uses of the flux coating coating on the electrode are: Producing a protective gas around the weld area Providing fluxing elements and deoxidizers Creating a solid coating over the weld as it cools Establishing electrical characteristics Adding alloying elements. You can find more at your local liberary >> book used Moder Welding, complete coverage of the welding field in one easy to use volume
E stands for Electrode,70 stands for tensile strength,1 stands for position of welding that is for all positions 8 stands for flux coating.
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.
It stands for electrode. As opposed to R ( rod) for gas welding or TIG welding. If it carries electrical current it is an electrode.
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.

If you are referring to the small unusable piece of welding rod that is left after welding, most call it a electrode stub.
