Is there any technical term called 'Dollymix' in pipeline welding?
I searched lot of literature but all efforts are in vein.I found that
many contractors WPS says 'Dollymix' progression !!!
Root pass uphill and remaining downhill called dollymix or root and
hot pass uphill and remaining downhill called dollymix? Is it a local
terminology or worldwide accepted one?
