The Dutch Welding Institute (Europe) supplies all over the world a wonderful program called "COSTCOMP" (Windows or Mac version) for the calculation of welding costs, based on a lot of welding parameters (filler metal, welding proces, welding position, amount of work under survey, gas, machining costs, ....)
Ik think the full licensed version is available for about 193 Euro en sent all over the world.
Go to the website and order a licensed copy or download a demo version :

I think you will love Costcomp as much as I do.
