Alloy 6 Weld Procedure
Alloy 6 Weld Procedure
(OP)
Can someone point me in the right direction. I need a weld procedure for overlaying Alloy 6 on a 316 shaft in 2 places on the shaft each about 3" long. The shaft will be undercut and will be straightened and machined after overlay.





RE: Alloy 6 Weld Procedure
I would suggest using ASME B&PV Code, Section IX as a guide for the weld procedure specification and for qualifying the procedure using the requirements in Article 2, QW-216, Hard-Facing weld Metal Overlay.
How will the shaft be straightened?

Stellite 6 is not the most forgiving material to use in this application. I would be concerned with inducing any bending stress in this region during straightening. If you need to straighten this shaft after local hardfacing, I would as a minimum perform a Liquid Penetrant test over each region that contains hardfacing and surrounding base material (1" distance) to assure you did not crack the Stellite 6.
