[MW:3059] Re: Formula for calculating SMAW & TIG Consumable Quantity & Gas Consumption

Friends ,

 

thanks for hte below guide line ,

 

Here i am looking for more details instead of knowing the whole volume of metal required .

 

I would lke to know the quantity for each type of electrode as we have for eg TIG root and hot pass followed with 7016 or

 

root is down hill and the other pasess are up hill ,

 

Do any one know how to find this or any Excel  program as most of the time need to depend of the supplier or welding formans .

 

Any helping hand will be appreciated .

 

Regards

 

Sujeet
