  • Welder's qualification

    According to EN 287-1:2011 point 5.4 (C),
    c) when a welder is qualified by butt weld test, a supplementary fillet weld test piece can be welded which shall be in a plate thickness of at least 10 mm and completed using a single layer in the PB position. For this supplementary test the welder shall become qualified for all fillet welds as given for the butt weld qualifications.

    My question is:

    1 - It's necessary to do a fracture test in the fillet weld?
    2 - The qualified thickeness for fillet weld is for the plate welded on the butt joint or on the fillet joint?
    3 - The qualified positions for fillet welds is the same as per butt welds?

    Thanks in advance,
