Guys I face high silicon content in ER70S-3 with high rejection repair rate,after changing of ER70S-6 we reduce repair rate.better purchase different manufacturer,and verify purging gas purity.

Replace ER 70S-6 with ER70S- 3 GMAW filler wire. Silicon content is 0.45 % to 0.75% for ER70S-3 and 0.8 % to 1.15 % for ER 70S- 6.
This is as per Aramco recommendation.
