Gentlemen,
The requirements for welding test specimens contained in ASME Section II Part C are not intended to be used as restrictions, requirements, or best practice for making production welds. The conditions set forth are intended to provide a “level playing field” for classification and comparison of welding electrodes and filler metals. Please read, for example, SFA-5.1 Annex A, Paragraph A6 and specifically A6.1 through A6.9.

Good information....Just a slight correction, It is on page no. 18 of 2007 ASME Sec II C.

As per the ASME Sec II Part C page no 11 in the general notes indicates weld layer shall be no more than 2.5 times of the diameter of the core wire.

More weaving will also cause more dilution !

EN standards recommend to limit the weave width to 3 times electrode diameter
ASME Code doesn't suggest the limit of weaving but as a good engineering practice, it is restricted to 3 x Electrode Dia in case of SMAW and 12-13mm Max. in case of FCAW / GMAW.
Effect of weaving:
1. Reduction in number of passes to be deposited
2. increasing the heat input
3. Higher weaving also results in reduction of shielding gas at the edges if the parameters are not properly set
4. It affect the side wall fusion, need to ensure the proper dwell time at the ends
5. Weaving speed need to be control otherwise causes the arc deflication
6. Higher weaving causes the reduction in impact properties

Dear all
if the weld weave length increased What will happen to weld and what
is the corrective action to be taken for weld
please advise
is any code reference, please tell me
