GTAW weld weaving

[simon lawrence]

Pls confirm that Weld weaving width ,  weld weave maximum how much we can accepted in GTAW process ?

[Jim Price]

You won’t find a specific para for weave width, other than ASME section 9, relating to your WPS that has been qualified.  Maximum weave width shall be as stated in your WPS (welding procedure). 

I believe this will be true for other Standards.

As per sec IX 2.5 times of the electrode dia can be allowed for weaving . In case of GTAW you can consider the tungsten dia in place of electrode dia.

As per Section IX, Weld Weaving is non essential variable for GTAW process. 

As such it is based on your WPS  which was qualified and recorded . If your job is having , Notch Toughness requirement, then dont go for more weaving which will reduce toughness properties. Go with multi layers .

Thanks

Sec IX, has nowhere said about weaving width for any welding process, but in Section 1 and Section 8, it has given for welding by SMAW, the weaving width may be 4Xcore dia.

In general practice ,the weaving width is limited to 2.5 to 3 times the dia. of filler wire used in GTAW

Nowhere found this is why you need to specify weave or stringer.

Weave width needs to be included.

Dear All experts,

Kindly conclude....the matter because many of us have same query for GTAW.

ASME SEC IX is lenient on weaving.WPS will guide this . Put the maximum weaving width  in WPS . With 2.4 dia , filler wire , a width of @12 mm is an acceptable width

Its depends on the PQR.
Weaving tends to increase the heat input on the material.

[Prakash Hegde]

Hi!

As such no code address about weaving but emphasis on heat in put

I) Excessive weaving increases heat input Good

ii) Good welding practices suggest about min weaving to reduce heat input viz about 2-3 time the electrode dia

Still  in spite of more weaving, if you can achieve good impact value No problem  and no body should object However experience says it is difficult to achieve consistence Impact result with excessive weaving

Regards

Hegde

Normal weaving by manual GTAW is @12 mm, which shall be addressed in WPS

Please refer PQR information. Width is advisable as per pqr record.
