Re: [MW:29851] Fwd: Regarding Weld area calculation for branch reinforcement as per ASME B 31.3

usually not, unless you really mesh up in the welding

In addition to my previous email, I would like to make my query more clear ..
1. If actual weld throat thickness is higher than the minimum specified in code , should we take the benefit of the extra weld area in calculation of reinforcement area ?
2. Does the extra heat input due to additional weld may distort the base metal and also affect the mechanical properties of weld ,HAZ and base metal ?

Hello experts,
As per clause 304.3.3 of ASME B 31.3 (Reinforcement of welded branch connections), Area A4 is the area of other metal provided by welds and properly attached reinforcement.

While calculating the weld area , the minimum value of tc=0.7 Tb or 6mm (1/4 in.) ,except that larger dimensions may be used if the welder has been specifically instructed to make the welds to those dimensions.

Now my query is --
In case if welder has gone with higher weld thickness and weld throat is coming more than 6mm, than the weld area for reinforcement should be calculated based on higher thickness or restricted to 6mm only ?

Thanks and regards
Atul Khatri
