RE: [MW:27721] Stellite 6 hard facing by GMAW process

Mr Prasad,

 

Stellite6 contains high amount of alloying elements. Melting and even distribution of these alloys , in low heat put process like STT, would be a serious problem. Hence conventional high energy process e.g. Plasma PTA  or GTAW or SMAW would be preferred depending on the component hard-faced.

Minor cracks' in Stellite -6 deposit are common. However could be minimized as suggested by Kannayeram Gnanapandithan

 

Take a look at this presentation , which may contain many useful guidelines.

 

Thanks.

Dear Experts,

 

Please share your experience stellite 6 hard facing by GMAW ( CMT/ STT ) process to achieve crack free deposit.
