hii everyone...according to ASME , can branch connections (stub-in or stub on) be considered as fillet welds or still thickness limits for welders should be applied on it.thanks...  

RE: welder thichness limits...

emrekop;
Why are you asking this type of question? Did your welders only qualify for fillet welds? Normally, welders are qualified using groove welds with test positions in QW-461.9 because groove welds qualify for fillet welds of all thicknesses and dimensions in accordance with QW-303.1.

emrekop,
A lot of fabricators standardize on test plates that are .5" thick so that their welder's qualified thickness is only limited by the WPS.  In our case we use a 6" sch 120.
