max amount of weave allowed with flux cored wire

what is the max amount of weave allowed with flux cored wires?

--------------------------------------------------

Sometimes if the welding is done according to a code such as AWS D1.1 , the code will list weave limitations. Sometimes not.

The engineering authority might impose a weave limit according to application and service conditions of the structure.

or they might impose a limit base solely on opinion.

I am not aware of any hard fast rule for weave width that applies across the board.

The weave widths are typically 3 to 4 X the wire diameter BUT:
I have never seen this actually published anywhere & LINCOLN for one will not publish a figure .

It has a number of effects on the end structure :
Higher heat inputs = lower impact properties

However depends on the use & needs - structural steel usually does not need high impact properties while a pressure vessel or pipe may need this so there are many parameters to be looked at .
The Approved & tested material using a particular consumable with a set of parameters will determine the weave widths ,

Testing can change widths though & wider weaves can be accepted provided the end weld gives the results sought

Hi i'm from middlesbrough in england and everytime i attend a test the inspector always say's i'm not to weave ! He wants beads everytime,shame theres not to many bead vids on here cause its a class site.

The maximum single pass layer width is:
5/8" in the F, H, or OH position for nontubulars.
1" in the V position for nontubulars, and H, V, OH position for tubulars.
