Re: [MW:33650] ER-70S-2 and ER70S-6

Approved WPS means you have to use the consumables as per Approved WPS. - ER70S-2 for production welding. 

If you have to write WPS using the same PQR , you can write WPS with ER70S-6 adding note in WPS that Mn content in wire shall  not exceed 1.6 %.

You can resubmit the above WPS  with ER70S6 and get approval for production  welding use.

Pl check read Customer Specification about consumable use.
