Dear expert, 

Good day. 

Recently I performed WPS for ER70S-G for nace requirement project. 

Based on welding consumable mill certificate as per EN10204 3.1, Ni <1% and these chemical analysis is conducted in authorised laboratory following the method specified in industrial code. It is laborious procedure and accurate. 

But when we perform PMI, Ni values shows 1.2-1.5, which client is questioning now. 

I did contacted consumable supplier and they are very certain Ni is less than 1%. 

Can anyone advice how should I handle this situation. 

Best regards,

Pravin Poornachandran
