smaw electrode costing

admin

I know this question has been asked but I have searched and searched and can't find the answer. I am looking for a chart of something to help me calculate approximately how many pounds of elctrodes I will need to purchase given the bead size, size and type of electrode, and how many feet of weld I have.We have a big project coming up at work and they need to be able to price it out but first they need to know what I need for electrodes and I'm not to sure how to figure that out for a large project about 700' of weld. Thats just a guess I am still doing the drawings and the calculation on exactly how many feet of weld it will be. I am just looking for something to put me in the ball park for costing and to know how much I will need to order.Thanks for any help you can give me.

Reply:Thanks thats a big help. Turned out I had all the info I needed to figure it all out I just had to actually open a book instead of jumping to the computer to try and find it I knew there was a reason why I buy so many text books all the time
Reply:There ar two variables to consider 1) weld size  2)choice of electrodeWeld size is no brainer - for a larger weld , more rods or larger a rod is requiredHeavily fluxed electrodes will produce more slag and unless they have added iron powder will not provide for extra bead length, but you will get less per poundIf you multipy the cross sectional area of the weld by 3.4, you will get the weight of th eactual weldeg. 3/8" fillet = .07sq.in. X 3.4= approx. 1/4 #/ft. X 700 ft = 175 # of weld.If you are using a rod with a heavy flux and you allow for a 1/3 weight loss for slag and stub ends, then multiply your 175# by 1.5 to arrive at 262.5 # of rod. For estimating you could go with 250# - 300#, depending on the application. Hope this makes some sense.
