You can also try preheating to lower rate of cooling to lessen cooling cracks as well.
For correct answer, require fuller information on the particular welding process.

--Hi ,Suryanarayanan,Some cracks are common with hardfacing alloys, due to their inherently low ductility. This could be minimized by using a Ni-based barrier layer for some type hardfacing alloys (Stellite-6, 12 ).I hope you'll find the information in the attachment as quite useful.What's the type of hardfacing electrode used for weld deposition??Appreciate your response.ThanksPradip Goswami, P.Eng,IWEWelding & Metallurgical SpecialistOntario, Canada
