Do you need the same mechanical properties as the base metal (4145) or you are overlaying to achieve more hardness or corrosion resistance...?
I mean what are your desired properties for finished weld...?

Ashish,We have in our facility the welding processes like SMAW, SAW, GTAW & GMAW. The reason behind to quality PQR is to weld AISI 4145 Base material for build up and machine back to drawing required dimensions.Ashish you are right, this material can be used for Tool joints, Drill pipe and Collars manufacturing purposes,because it meets to API minimum Yield strength requirements.Regards,MubeenOn Fri, Jul 29, 2011 at 9:05 PM, ashish baviskar <ashishqci@gmail.com> wrote:
