Dear All,
Good Day.
Please inform me what will be the Minimum length of the taper for butt weld between plates of 10 mm and 20mm Thickness.
Please refer Fig. 2 of the attachment and inform me--
whether length of taper will be distance between edge of plate ( The point from where tapering is statring ) to root face of the bevel i.e L
OR
Length of taper will be from edge of plate ( The point from where tapering is statring ) to the point where thickness of the thicker member becomes equal to thickness of the thinner member i.e L1
What is the maximum angle allowed for tapering.( please refer Fig. 1(a) of the attachment)
Thanks in advance.
Regards
Asad

dear asad,
for welding unequal thickness, the taper must be in the ratio 4:1.
refer ASME B31.4 or ASME B31.8 for details.
generally the weld height must must be 0.5 x lower thickness.
