    How Can I Estimate Amount Of Welding Rods Required For A Large Welding Job?
    Thanks

    Welcome to the forum,

    calculate the length of the total welds and their size. Multiply that with the weight of the material. Divide that weight by the weight of the filler per unit (inch, foot, rod,etc). calculate the over burden on the job such as loss due to waste, stubs, or damage. I use 10% for tig, 20% for stick (mostly stubs, I tend to leave them a bit longer) and about 8% for mig. Now if the job is really big I will adjust that to a standard poundage based on my experiences in that type of project.

    You're experiences may yield a different percentage as you go along.

        most of the time they don't include it. They use to and I don't know why they stopped. You can use the standard weight for materials such as .283 pounds per cubic inch for steel. Verify the number it's off the top of my head. Just get close to the alloy your working with.
