[MW:34077] Re: Ss to P91 Welding

John

Problem seems to be with Welder and Power source.

Give training /practice of running  welding of ENiCrFe2. 

After his practice , he can weld sound weld .

Ni consumable weld metal is sluggish due to its viscosity(Higher Ni %)

The speed /skill is important.

Thanks

Dear Experts,

We are doing welding for Sa335 P91 to A182 F316 material. As per Wps Gtaw + smaw is welding sequence. 

Filler is ERNICR-3 And ENICrFe3. But Electrode we are using ENiCrFe2. 

During Gtaw welding there was no problem smooth welding but once me started Smaw than the electrode is not getting fused properly material is thrown out. 

We are maintaining proper interpass continously as per Wps. 

Kindly provide us valuable feedback.

Thanks & Regards,

John Rodrigues
