Weare or string

[haundpv...@gmail.com]

I am wondering if anyone knows what the maximum weave is for SMAW (specifically ASME Section VIII Div 1). For some reason 3x is sticking in my brain, but I would like to know where to find it in the ASME Codes.

u can find in PW40 also, it is 4Xcore dia not 3

THANKS & BEST REGARDS,

As per ASME Section VIII Div1, 

Please refer to the para UCS-56 (Requirements for Postweld Heat Treatment) para f(4)-a

Mentioned as maximum bead width shall be four times the electrode core diamter.

Best Regards,

Chandra

Incorrect information.

 

First PW-40 is in Section I not Section VIII, so does not apply top question asked.

 

Second, PW-40.3.4 (d), which references bead width, applies only to repairs performed by the temper bead or half bead technique.  Very specialized application.

 

Third, there is no restriction otherwise on bead width in either Section VIII, Division 1, or Section I. 

 

One will often find such restrictions in customer specifications. 

 

Careful where you walk.  Free advice is worth just that.

Again, incorrect information.

 

Section VIII, UCS-56.f.4(-a) applies only to repairs avoiding PWHT by use of temper bead or half bead technique.  See UCS-56.f.4(-c).

 

There is no weave width restriction for general welding in either Section VIII, Div. 1, or Section I.

 

Do not apply special case requirements to general welding.  A recurring mistake made by many.
