All SMAW electrodes have letter and number designations. Those used for welding steel have a letter E (Electrode) followed by 4 or 5 numbers and may be followed by number/letter designations. Basically the first 2 or 3 numbers give you the tensile strength of the weld deposit in thousands of pounds per square inch ie: 6013 refers to 60,000 PSI of tensile strength. 11018 would mean 110,000 PSI of tensile strength. The next number stands alone ie: 1 means it can be used in all 4 positions flat,horiz.,vert.,and overhead. The last 2 numbers are taken together and designate the basic ingredient of the coating mix plus what type of electrical current is to be used. ie: 13 can be used with AC or DC straight/reverse polarity current. A chart can be obtained to tell you what the basic ingredient in the mix is although in most instances this is not that important. Some steel electrodes have letter/number designations after and usually refer to the batch number so that any problems encountered can be traced back to production. ie: E-7018 B2
It the same as 6013
6013 reffers to welding electrode specification. 1 st two digit stands for load / stress carrying capacity . next digit stands for welding position. and last one for welding rod ,flux material composition.
E 6013 E - Electrode 60- 60000 psi Tensile strength 1 - All position 8 - Basic lime / Iron powder flux
It stands for electrode. As opposed to R ( rod) for gas welding or TIG welding. If it carries electrical current it is an electrode.
yes
E - Stands for Electrode 60 - 60,000 tensile strength. 1 - in all position welding can be done 0 - cellulose
I believe you are confused. The number reading on the top of the welding electrode is simply an indication of the characteristics of that welding rod. Ex. 6013 means 60 thousands pounds of tensile strength per square inch,1 indicates that is an all position rod, and 3 is the mineral compound of the rod. Hints 6013. The welding rod size is indicated in fractions of an inch. Ex. 1/16, 5/64, 3/32, 1/8, 5/32 etc... Hope this has been helpful to you. Refer to the American Welding Society for further information.
6013 is normal arc electrode which is used for light jobs like sheet welding or tank making but when it comes to heavy construction jobs where strength required is more 7018(Low Hydrogen) Arc Electrode is used like boilers, heavy structures etc. Working with 6013 is far easier than 7018, which requires welder's skills. Neatness in finishing is also more with 6013 than 7018. any further info. on construction : nangalsuri@rediffmail.com Surinder Singh
how do you calculate welding electrode consumption
1 stands for all positions.
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.
The designation E6011 means: E=electrode 60=60,00p.s.i.tensile strength as deposited 1= all position 1=coating make up
