Dear All
Plaese help me, I not understand requierement 4.31.1 of AWS B2.1-2009, could someone help me with the interpretation.
I sorry because my native language is spanish.

Thank you

4.3.1.1 If the welding procedure specification (WPS) for
welding the combination of base metals specifies the
same qualification variables, including electrode or filler
metal, as both WPSs for welding each base metal to itself,
such that the base metal is the only change, then the
WPS for welding the combination of base metals is also
qualified.

Base metal "A" would have a WPS for welding base metal "A" to base metal "A', and Base metal "B" would have a WPS for welding base metal "B" to base metal "B".

But, when welding Base metal "A" to Base metal "B".... this combination of welding the two different base metals to each other is only qualified to weld to each other if the WPS for welding base metal "A" to base metal "A', and the WPS for welding Base metal "B" to base metal "B" have the same qualification variables, including electrode or filler metal.

I hope that I haven't added further confusion.
