Up Topic Welding Industry / Inspection & Qualification / Use of Unlisted Materials for Welding as per AWS D1.1
- - By nithindsilva4u Date 01-17-2017 09:38
Can we use the provision of referring to equivalent material grouping as per ISO 15608 (as specified in AWS B2.1), when writing a WPS without qualifying the unlisted materials separately.

Backround :
Production joint is made of EN S275JR to S355JR.

Qualified WPS/PQR with A516 GR 70 as base material in PQR exists. Can we make a WPS stating that all Group 1 materials can be welded including S275JR and S355JR, by referring to the grouping system provided in AWS B2.1?

Seek your Engineer's approval whether you can apply Clause 3.4 of D1.1
