hardfacing and welding cost approaches ?

Date 05-06-2010 22:41

i want to know what is meant by hardfacing in welding ?
as i read when you determine the cost of welding : there are three approaches one is called cost per unit,cost per length , and cost per weight ( which the article said it is used for hardfacing applications requiring significant quantities of metal to be replaced by welding ) so i want to know what is the difference between them and what is meant by hardfacing application ??
here is the site for welding cost approaches : http://weldingdesign.com/processes/news/wdf_10760/index.html
thanks in advance

Hardfacing is a welding technique to harden an area, rebuild old, worn-out components, and just about what it says.
They were using it as a prime example to figure welding costs per weight.
Hope this helps
