Miller PipeWorx RMD & Pro Pulse machine V’s Weld procedures

Hi,

Few points.

There are 4 main types of transfer modes in GMAW process, dip, globular, spray and pulse. 

So if your WPS have been qualified with say spray trans, when you buy new machines and they have pulse trans you are required to re-qual your WPS. 

If qualifying to a pulse proceedure, this procedure becomes pretty much a machine (or type) specific.  As a change in any pulse parameter is a change in essentail variable.  In my experience many w/shops have invested in one or two pulse machines but not many use them in pulse mode as any procedure quals on them are not transferable across the rest of there welding machines. 

Hope this helps.
