[MW:17817] Welding and cladding SA-516 Gr. 60 + AISI 410S

I have shell 20mm thick ( SA-516 Gr, 60 ) and there must be cladd AISI 410S 3mm    
Could anybody tell me which filler i can use, for SAW  and GMAW?
GMAW i  planning use for flanges and tubesheets ( after i overlay tubesheet - what is procedure for welding tube to tubesheet? )
Also PWHT has been asked by customer after overlay. 
Can anybody tell the effect of PWHT on SS 410S overlay? 
What will be the the safe range of temperature of PWHT?  ( Also recommended temperatures and times, holding cooling...)

Best regards,
Branko Ferencak
