Up Topic American Welding Society Services / Technical Standards & Publications / Question regarding WPS & PQR - AWS D1.1-2015
- - By binhjack (*) Date 11-07-2016 03:27
Hi all,

According to [4.8.3 Base Metal Qualification: WPSs requiring qualification that use base metals listed in Table 3.1 shall qualify other base metal groups in conformance with Table 4.8].

I have WPS & PQR using the base metal ASTM A572 Gr.50 (thickness 25mm) for qualification.

Can I use the WPS & PQR to apply for other base metal groups in conformance with Table 4.8 without making a new WPS?

For example: I use it to apply for the product using base metal ASTM A36 (thickness 30mm)

From Table 3.1 - ASTM A572 gr 50 is a Group II base metal.
From Table 4.8 - Any Group II to Any Group II qualifies the WPS for Any Group II to any Group II, Any Group I to Any Group II and it qualifies for any Group I to any Group I

ASTM A36 less than or equal to 3/4 inch thick is a Group I, any ASTM A36 greater than 3/4 inch is a Group II base metal. Thus pre the previous paragraph, your WPS is qualified for ASTM A36 to A36 for all thicknesses.
