Other than ASME Sec I? yes in ASME Sec VIII Div I (UCS-56) where you can find a sentence " The maximum bead width shall be four times the electrode core diameter"
Just compiling as many codes or standards that address deposited weld bead width.
Thank you Joey, that does apply but only to weld repairs to P1 Gr 1,2,3 and P3 Gr 1,2,3 matls..
And thanks, Doug for the D1.1 (2010) reference. Although 3.7.2 describes the limits, a welder really isn't limited to an electrode core diameter relationship to deposited weld bead width. I do see the reasoning behind limiting the size in Fig 1 as being stress factors in the T-joint configuration.
I recall reading a discussion about weld bead width at one time. I believe it was in a engineering forum somewhere. If I recall correctly, weld bead width and heat input had some type of correlation to weld failure. What I do remember is, if weld bead width were to become an issue, it would be advisable to consult the engineer.
QCRobert, I believe you will find this topic addressed as a part of impact requirements within ASME IX for those ASME Codes that require impact testing. I'm saying this from the top of my head as I don't currently have access to my ASME IX so apologies if I'm mistaken.
Sorry for the old post but related to bead width, 2 1/2 times is often mentioned. That requirement is often found within the filler metal specifcations for qualification of the test welds. A/SA5.1, 5.5 etc.
However that does not mean it is required for fabrication/repair. Its just what is controlled during qualification of the filler metal.
