Weld Metal calculation

[inconel]

Hi everybody,

I am looking for weld metal(weight) calculation for pipe welding.anybody having any excel work sheet or worked out method ,please share it over here or send to my e-mail address mentioned below.I have to order electrodes for production welding. Following is the dimensions of the joint .Thickness of pipe 18 mm, 70 Degree angle single V-Groove,1 mm root face,1.5 mm root opening. I have calculated total volume of joint all around pipe.then divided it by density of weld metal(mild steel) to get mass of the weld metal required to fill the groove. But the result is not correct due to some unit conversion mistake.I am looking for help from all the members over here interested in this subject.I am new in welding engineering and don't have much idea about this .Expecting help from my seniors and friends.



Thank you in advance
