Re: [MW:28143] Weld bead length

Greetings,

Debate regarding weaving starts with fact that many of WPS  states weaving as 3 times diameter, without any particular need. However, for 9 mm width, I believe no standard mandates multi-weave. At maximum, heat input can be measured and co related with pqr value.

Dear Gentlemen,

We are doing welding of LTCS materials, while welding some of the

joints we welded final run in single bead which is as per approved

WPS(3 x electrode dia.)  Our client is asking us to do multi bead

welding above 6" pipe even though the gap in groove is below 9 mm. We

are using 3.15 electrode to do the final run. We are maintaining heat

in put in control. Please clarify me whether it is correct or not?

Thanks & Regards

N.Kiran kumar,
