6.7.2.3 Ogalificat ion Ranges. A change in any of the essential variables that exceed the limitations of 6.5 requires requali licat ion.
Fillet Welds
Qualification Testiiig. For a fillet weld WPS not conforming to Clause ., qualification testing shall be required in contormance with Table .2, Item (1 O)(b) or Table p.2. Item (I O)(c).
Test Assemblies and Examination. Two test assemblies shall be prepared. welded, visually inspected, and tested using either sheet to sheet or sheet to supporting structural member described in (1) or (2) as follows:
(1) Sheet to Sheet. Each test assembly shall conform to Figure .2A.
(2) Sheet to Supporting Structural Meniber. Each test assembly shall conform to Figure .2A.
(3) Eaniination. A weld shall be acceptable lithe following criteria are satisfied:
(a) No weld metal cracks shall be visually detected after bending. or
(b) Weld metal cracks are visually detected after bending and
(i) The fractured face shows no visually detectable discontinuities (e.g., slag, porosity). and
(ii) The weld size ç, is equal to or greater than the sheet steel thickness NOTE: Base ineul cracks shall he ignored.
(C) After visual inspection of acceptable welds, the two pieces shall be completely separated by either bending the sheets or by hammering a wedge (see Figure .2A) until either the weld or sheet metal fails.
(d) The fractured surface shall show complete fusion at the root of the joint.
..Z.1.3 Qualification Ranges. The validity of qualification shall be as follows (see Figure .2B):
(1) T-joints shall qualify for lap and T-joints.
(2) Sheet steel to supporting structural member qualities for sheet steel to supporting structural member for a given position of welding and thickness of sheet steel.
(3) Sheet steel to sheet steel qualifies for sheet steel to sheet steel, and also sheet steel to supporting structural member for a given position of welding and thickness of sheet steel. AWS D1.3/D1.3M:2018 pdf free download.
